In a Topside blizzard the bewildered Nomads make their way into North Col where Geneva guides them to the holodeck. Through a combination of deduction and good luck the Nomads propel themselves forward in time to Haven where their reappearance is monitored by Sutch. Sutch, who is under instructions from Dr. Pretorius to take Noah and Becky to a place they can never return from, instead reunites them with the Nomads. He too will now join them in their battle to defeat the Protectors and Dr. Pretorius. Together they formulate a plan to destroy the Thunderstone. Noah and the Nomads move on the unprotected Thunderstone motherlode. As Sutch and Sundance hijack the Beast and liberate the enslaved work force, Noah, Becky and the other Nomads spread salt out at the motherlode base. The showdown has begun! Tao and Dr. Pretorius move to protect their Thunderstone, their future. Tao, now revealed to be a hologram himself has targeted Noah but Becky's quick thinking saves him. Tao flickers wildly and disappears! Dr. Pretorius, his life's work destroyed pleads with Noah who, raising a Masergun, ignites the salt and with it the motherlode. The war over, Noah throws down the Masergun. Behind him Dr. Pretorius is left engulfed by the flames. Tranquillity in Haven, the Nomads and animals are free. Noah, his family and the citizens return to North Col — there must be a past so there will be a future. As Noah hangs up the PH-Ts he smiles with the memories he will hold on to. In Haven Arushka rides proudly on Moshi. Before her the landscape is filed with the animals of the world. They will live free once more.

Noah and Arushka white-in, arriving in some bush country abundant with wildlife, and to Arushka's delight, horses. Her reverie is shattered as gunshots ring through the air. An outraged Arushka runs to the noise and confronts Bully and Mac who are trying to cull kangaroos. Not happy at being interrupted they warn Noah and Arushka off. They are saved from these lads only to be imprisoned by their saviour, Duane, an alien fanatic who saw them arrive. This time they will have to believe him, he has proof! In Haven, the Shadowmaster has contacted Tao, demanding that he make the capture of Noah his first priority. Travelling to the Deep Road, Tao forces Ferris, a young timid boy, into spying on the Nomads. He wants to know where they hide. Free again, Arushka and Noah prepare to leave. But things go terribly wrong and Noah arrives back in Haven in the company of dozens of animals, birds and the sheepdog Dolly — but without Arushka. Arushka is alone and trapped in the past!

Noah discovers the secret to making E-Delta fertile, but first he must stop the Thunderstone Ring from crushing Earth. The strain of executing the strike on Earth has made E-Delta unstable and the kids are evacuated from the Bioplex in the hope that salvation will arrive before the red giant rises. Noah must bring the thunderstone ring through space-time in a crazy attempt to save two worlds and right past mistakes.

Noah must find out what happened to the lost parents of the E-Delta kids to keep Earth from being put under attack by E-Delta. Little does he know that Ivan has imprisoned drako along with the other nomads. Ivan sends the robot drone, with the canister, through a wormhole to the thunderstone ring surrounding earth. noah and his family shelter from a hail of falling rocks, the first sign that the asteroid belt is spiralling in towards the planet Earth.

Noah and Drako are put in an uncomfortable situation when a wormhole opened by Liz brings them back to Earth alone. Ivan seizes the opportunity to assume leadership and take over the strike on Earth. Drako must reassess his opinion of Noah when he saves him from drowning. The two boys, once mortal enemies, strike a deal that will benefit E-Delta and save Earth from destruction.

While the young Nomads set up camp in a cave shelter, Noah and Arushka infiltrate the Bioplex. The key to Drako's strike on Earth is the Thunderstone canister. In the process of seizing it, Noah meets a hologrammatic version of himself at 45 years of age, who sheds some light on why the E-Delta colony went bad.

Moshi saves Drako from being trapped outside the Bioplex under the red giant sun. Ivan loses confidence in Drako's leadership and dishes out his own punishment to anyone who helped Arushka escape with the animals. Noah and Arushka prepare to return to E-Delta to rescue their friends and put a stop to Drako's evil plan. Kwan must continue to pretend he stayed behind on E-Delta on purpose. How long will it be before his true loyalty is discovered by Ivan?

Mr. Greenway confesses to helping Drako steal the animals and gives Noah the final clue he needs to piece together what Drako has in store for Earth. Arushka and Kwan's plan for getting themselves and the animals back home goes horribly wrong when Drako decides to take Moshi out for a ride.

Apra commences construction of a robot drone which will deliver the E-Delta kids' revenge on Earth. Arushka is furious when Drako brings animals from the Wildlife Reserve through a huge wormhole — how will they survive on E-Delta? Meanwhile, Noah and Liz are "borrowing" equipment from their now off-limits lab in order to construct a makeshift wormhole transporter.

Chip helps Noah escape from his guarded home and the pair quickly discover their friends have been taken to E-Delta. Clio and Curly join forces to help Kwan and Arushka rescue Moshi. With the Bioplex's energy reserves running low, Drako decides to returns to Earth to deliver Noah an ultimatum: the safe return of his friends in exchange for a canister of Thunderstone. Drako double crosses Noah, taking the canister and destroying Earth's only wormhole transporter.

After Drako's raid, Horizon Foundation security orders Noah be confined to his home for his own safety until the crisis is over. Chip finds Clio in the Wildlife Reserve and together with Arushka and Chip, begins to teach Clio about animals. In return, Clio shows them that not all E-Delta kids are bad. While confined to home, Noah searches the files Drako stole in an effort to determine what he came to Earth for. When Drako returns for Clio, Kwan and Arushka (along with Moshi), follow their new friend through the wormhole to E-Delta. Kwan is taken prisoner by Drako while Arushka flees into the hostile wasteland. Apra decrypts the files stolen from the Horizon Foundation, revealing the location of a very special asteroid in orbit around Earth. With a deadly wall of sand approaching, Arushka has no choice but to return to the Bioplex. Drako takes Arushka in but leaves Moshi out in the storm.

Drako and his gang make another raid on Earth, this time targeting the Horizon Foundation where Noah works. After forcing Noah's mother to give them access to the Foundation's encrypted computer files, they are surprised by Arushka while trying to escape with Noah. Arushka stops Drako from taking Noah back through a wormhole and in the confusion, a young member of the raiding party is left behind. Clio is alone and terrified by the strange beasts in the Wildlife Reserve.

Noah meets Curly, a grizzly old hologram who tells him why the E-Delta kids want revenge against Earth and their mortal enemy… Noah Daniels himself! He and Chip must break Arushka out of the Bioplex and get back to Earth before anyone discovers his identity. Meanwhile, on Earth, the animals in the Wildlife Reserve are under threat with Arushka away.

Arushka is held captive on the planet E-Delta, where the Bioplex structure is the only thing that stands between the inhabitants and their hostile environment. You can't last long outside without an oxygen pack and during the time of the red giant sun, you can't last at all. Drako, the handsome leader of the E-Delta kids, advises Arushka to get used to her new home — she's sixty million light years from Earth and any hope of rescue. Noah and the Nomads have other ideas as Chip impulsively jumps through Noah's experimental wormhole. Noah pursues him and the two emerge on E-Delta and make their way inside the settlement after rescuing one of the young colonists.

Noah cannot believe that he is, or that in the future he will become, the creature that stands before him. The Shadowmaster tells Noah that it is time he learnt the truth. They both white-out of North Col and arrive in Haven. The Shadowmaster challenges Noah — was it right to bring the animals to Haven? They outnumber the humans and will continue to breed. Good, says Noah defending their rights and place in the laws of nature. The Shadowmaster lauds the wonders of Thunderstone. Its power will bring the human race back to his former greatness! It cannot be wasted on animals. "If I am to become what you are", says Noah, "why can't I change the future and so change myself? What is happening to me? To the Nomads?" But the Shadowmaster sends him back to North Col, back to rats scurrying everywhere, panicking citizens who don't see, as does Noah and his family, that the rats are in fact an illusion — they are holograms. Into this pandemonium the Shadowmaster appears and laughing mirthlessly, removes his mask revealing himself… it is Dr. Pretorius, he is the Shadowmaster!

2020 is the year in which Noah Daniels lives with his family. Back in 2002 a comet Nemesis destroyed the Earth's surface along with humans and animals. The few that survived live underground in a place called North Col. Noah is gifted in ways, but it is his fascination with the holodeck with proves to be costly. The holodeck with was once used is now left to gather dust, until Noah starts it up and lands in Haven.

With the scaped lion on the bonnet of the police car, a horrified and amazed crowd watches as Arushka calms him. She achieves instant star status when she gestures the animal back into his cage. Ivana arrives with Moshi and speaks quickly with Arushka. She understands the future Arushka comes from and asks Arushka to take Moshi with her. Using power from a nearby news van, Noah activates the PH-Ts and in a flash of white light Arushka, Noah and the beautiful black horse Moshi are gone! Instantly they reappear in Haven and the first animal brought through time has arrived! Becky, experimenting with her own PH-Ts hoping to discover what happened to her brother, shrieks with delight as she witnesses their time journey. He's alive! Pretorius quizzes Becky about what she saw but he and Beck'y parents give little credit to her story. Becky wants to try to recreatd the conditions at the time of Noah's disappearance but is not allowed. Lost without Arushka's leadership, the Nomads, spotted by Tao's mobile Sentinel, are captured as they flee to safety. Noah, Arushka and Moshi launch into a rescue mission. Noah hijacks the Beast while Arushka liberates her friends. The Protectors are closing in on Noah when Arushka and Moshi gallop into the fray and scoop Noah from the Beast and on to freedom! Arushka fears that Moshi must not be the only animal in the future of the world. She tells Noah if he helps her she will help him get to a power source to effect his escape home. What choice does he have?

Arushka, still trapped in the past and hunted by Bully, Mac and Duane, saves Mac from being trampled by a wild brumby. Awed by the mystical effect she has on the animal, they listen to her story. Duane and Mac agree to help her but Bully standing alone is not to be trusted. Tao has dispatched his Protectors to Noah's arrival co-ordinates. As they close in on Noah, Dolly sends them scattering, terrified as they have never seen a monster like this dog. Noah must get to a power source and go back and save Arushka… who is with Duane and Mac rounding up horses when Noah whites-in. In a race against time, Bully having called the police, Noah powers up his PH-Ts and he and Arushka, now astride one of the horses, white-out. Tao is preparing to demonstrate his dominance over the animals that have his troops cowering when Noah, Arushka and the horses arrive in a whirlwind of light and dust and power. The Protectors again run scared from these strange beasts. More animals have arrived in Haven!

In Haven of 2085, Arushka rides Moshi, her black mare, through the Riverlands. She's inspecting the contented Animals which she and Noah have transported to the future to avoid extinction. Dolly follows at a distance… But we see the faithful sheepdog distracted and lured away. Above the North Col of 2020, the Impact Winter produced by the Nemesis Comet still prevails. Noah discovers Dolly, terrified and half frozen in the blizzard. How had the dog travelled back through time and who sent her? Arushka returns to the compound, where the Nomads now live as a settled community. With their enemies vanquished and the contentious mineral Thunderstone wiped from the face of the Earth, Haven is a peaceful place. An eccentric old peddler, Monsoon, visits with gossip about the comings and goings of new settlers and about the weather, which in Haven has lately been extreme and unpredictable. Dolly is discovered in North Col by the authorities and is condemned to banishment in the snow. To save her, Noah breaks the new rules which ban time- travel. He breaks into the sealed Holodeck and used the PH-Ts to return again, with Dolly, to Haven. He arrives at the height of the storm and helps the Nomads save their hut from a lightning-felled tree. Then there's time for a reunion. But the Dolly mystery is unexplained and some unidentified figures are watching them through the trees.

-Noah is quick to notice that there is dissent among the Nomads. Now that they're no longer on the run from a common enemy there's a restlessness. Old Monsoon visits with his wares and tall tales and wheedles an invitation to stay the night. In the morning, Noah discovers he's taken his PH-Ts and he and Arushka set off to the get the precious time travel device back. Meanwhile in North Col, Becky tries to cover for Noah's absence by producing the Noahgram, a hologrammatic version of himself which Noah has recently created. Its behaviour creates bizarre situationsand the ruse is quickly discovered. Chip, annoyed at being left behind, determined to catch Monsoon by himself. Against Kwan's warnings, he saddles up Moshi, Arushka's majestic black mare. Arushka and Noah catch up with Monsoon and demand the PH-Ts returned, but the crafty old man denies having seen them. Meanwhile, Chip is having trouble with Moshi—but he hears the rattle of Monsoons pots and pans in the distance and manages to spur the horse on … into the woods. All is silent and there is no sign of Monsoon, but something in the bushes frightens Moshi. She rears and Chip is thrown into a pit of quicksand. The frightened horse bolts, leaving Chip alone and helpless, sinking further into the quagmire. What could have frightened Moshi so much she'd leave a Nomad in Peril? Alerted to the danger by Moshi, bridled but riderless, Noah and Arushka race to Chip's rescue. But they're too late… as Chip disappears below the sand four strangers to Haven haul him out—Myah, a barbaric looking young woman and her three brothers, Rorden, Tod and Lyal. Not only have they saved Chip's life, they also have the PH-Ts, which Rorden reluctantly relinquishes. The Nomads and the new family pledge a wary friendship. With the PH-Ts returned, Noah must face the fact that there is no source of power for them in Haven. How will he get back to North Col?

-As dry electrical storms prevail in Haven there is growing concern about the changing climate. Noah devises a plan to harness the lightning, which strokes most often on Razorback Ridge, and so powers his PH-Ts. Monsoon wins back favour in the Nomads' compound by bringing in a wounded animal and half of a weathered amulet. Kwan produces the other half, given to him by his long-lost mother. With the prospect of reuniting with her, Kwan bids the Nomads farewell. Though his hopes are dashed, a heart-broken Kwan has too much pride to return to the compound. Monsoon, meanwhile is spooked by a visit to the family. It seems these people can communicate with each other telepathically. Up on Razorback Ridge, Arushka insists Noah test the PH-Ts before using them on himself. The stand-in scarecrow is burnt to cinders as lightening is channelled into the PH-Ts. Nevertheless Noah ignores all protests, reconfigures the equipment and successfully time-travels back to North Col. Noah's family are relieved to see him but the North Col authorities thrust him into the detention centre for breaking the time travel ban. Myah is lurking in the North Col sludge pipes. How and why has she accompanied Noah on his time travels?

Syndia, still fuming, pronounces banishment for Noah when he returns. In Haven, Noah is awaiting the next lightning strike. Myah pleads with him not to leave, making vague promises of power and success. She is left behind angry and frustrated, as Noah white-lights out once again. Noah arrives home secretly and employs Becky's radical plan to avoid banishment: he uses the PH-Ts to travel 24 hours back in time to the detention cell. In the re-run yesterday, Syndia storms in and finds Noah safely locked away, rather then discovering Russell. Back in today, Becky is delighted with the success of their plan, but Noah is shaken by its implications. He swears never to use time travel technology to change history again. Meanwhile in Haven, Geneva falls into an animal trap — who would make such a thing in Haven? Chip runs off to alert the others but doesn't see a herd of wild brumbies approaching. While Lyal and Rorden muster the animals towards the trap, Tod, the youngest of the family, discovers Geneva and places himself between the trap and the stampeding animals. He manages to divert them and pulls Geneva to safety. When they spot the Nomads approaching, Rorden and Lyal flee. Tod is brought back to the compound as a prisoner. As a hunter of animals he is an enemy to the Nomads. But his charms are not lost on his warden, Geneva. She is convinced Tod has learned his lesson and successfully argues for his release. At their campsite, Myah rips into her brothers for getting on the wrong side of the Nomads. They need them… but for what?

There has been no rain in Haven for a long time and Arushka is worried about the animals. While checking up on them she sees Rorden, the most eccentric of Myah's brothers, scurrying out of the rocks below Razorback Ridge. She and Sundance return to the spot to investigate. They discover Rorden's Grotto, filled with weird equipment. Meanwhile Myah is conducting a few investigations of her own. Once again she uses the Nomads goodwill to her advantage and is snooping around the Beast, an old vehicle still filled with gadgetry of its precious owners, the Protectors. The brothers return to their cave and catch the unsuspecting intruders. Arushka and Sundance have no means of escape, locked in a primitive cage. What is the strange family up to? Above North Col, Noah finds a pair of modified PH-Ts, exactly where Dolly was found. Somebody, sharing his knowledge, must have sent her into the past deliberately. Risking the inevitable censure, Noah once more travels to Haven to find the truth. The Nomads have received Arushka's message from Prince, a friendly kestrel. Noah and the gang embark on a mission to rescue Arushka and Sundance. In the struggle between the Nomads and the brothers, Sundance is recaptured. And now Rorden has got hold of the PH-Ts. At last, he says, dangling them in from of the caged Sundance, I have a human subject for my experiments.

Rorden prepares to send Sundance on an experimental time trip. In a failed rescue attempt, Chip is caught up in the white- light along with Sundance. The two boys arrive in a present day dance club. Chip is fazed by his surroundings, but Sundance finds the rhythm of the music intriguing and has soon caught the eye of a pretty girl. Myah returns to find the brothers in a panic and is furious about their inept behaviour. Not only have they damaged the family's relations with the Nomads almost beyond repair, but Myah is forced to ask for Noah's help in retrieving Sundance and Chip. Noah's assistance is not cheap — Myah has to answer his questions. Myah reveals that she and her brothers come from the Silver City, a future metropolis — the pride of Haven in 2235. Noah extricates Chip and Sundance from the club, just in time to avoid the wrath of a jealous boyfriend. On Razorback Ridge, Myah and her brothers are part of a welcoming committee, but the Nomads want nothing to do with the meddlesome family.

The Nemesis Comet is hurtling past the moon towards Earth. It is so close now it can be seen looming in the skies above the General Store, where the Nomads are refueling the Beast. The Nomads head straight for the Cortillo Plain installation. Sundance, an uneasy rookie driver, steers the Beast across country and through the installation's security fencing. Meanwhile, Myah and her brothers have commandeered a security vehicle and are sneaking past the installation's guards in a more subtle fashion. In the Operations room General Cardell ignores a young scientist's warnings about the disastrous effect his nuclear rockets will have on the Nemesis comet. The young scientist is Liz Frankiln, Noah's mother! This is an added problem for Noah and Arushka, who are hiding in the shadows. If they don't get the young Liz on a helicopter and back to the safety of the underground North Col research facility, Noah might not even be born! It's less then an hour till the rockets are launched and the Nomads are heading for the radio telescope. Arushka is on Moshi, riding alongside the Beast. Myah and the brothers, having failed to waylay Noah at the installation, are in hot pursuit in the security van. Arushka wheels them off course, causing their vehicle to overturn on the rocky desert plain. Noah aligns the Beast's projector with the radio telescope reflector. Myah, dishevelled from the crash, is determined to stop Noah from saving the Earth from the impact and wasting the precious Thunderstone Cube. Arushka wrestles her away from the Beast's controls, leaving Noah free to make the frantic last minute adjustments. As the rocket launch countdown nears zero, Noah hits go, sending the beam skywards. The Nemesis Comet is shattered and its blue rock dissipates harmlessly into space. While everyone else is staring at the spectacle in the sky, Myah and her brothers look down in horror. They are literally disappearing! And in Haven the Daniels and Monsoon watch the animals disappear and the landscape change. Now!… says Becky and dons the PH-Ts Noah left for her. The Daniels and Monsoon arrive at Cortillo Plain for a brief reunion with Noah and the Nomads before Noah makes a final command and they all white out together — side-stepping time to somewhere in the future.

Noah and Arushka stare gob smacked at the huge creature before them. This is a circus in 1999 — they have gone back too far! Arushka doesn't hear or care about Noah's concerns — these are real animals not just images on a wall. She never wants to leave. Noah tells her in a couple of years the animals and everything else will be gone when the Nemesis Comet strikes. Noah sets off to find a power source, leaving a saddened Arushka to look around. All of the animals are amazing but when she meets the beautiful circus horse Moshi she is totally captivated. As Noah drags Arushka away from the circus they meet Sophie and Mingus, a pair of animal liberationists set on freeing the circus animals. Whilst trying to prevent the animals from escaping, Noah and Arushka are caught and accused of the break-ins. In North Col, a quantum aberration convinces Becky that Noah may have time-travelled. Tao roars across the Red Desert in the Beast, telling Jett about his latest weapon — the mobile Sentinel tracking device. They can run but they cannot hide! Noah and Arushka are being escorted to a waiting police car when a lion escapes its cage. The crowd panics but an entranced Arushka is captivated by the beauty of the King of the Jungle.

Still trapped under the Beast trailer, Noah and Sundance see Arushka approaching on Moshi. Tao, impressed with her bravery, and interested in Moshi, steps out to confront her, giving Noah and Sundance the chance to get inside the Beast trailer and sabotage the map co-ordinates that would lead to the capture of the Nomads. With the mission accomplished Noah and Sundance say their farewells, Noah heading off to the Keep and a power source for hs PH-Ts. Tao dispatches the Protectors, offering a reward, to whoever captures Noah. The glittering prize of a vehicle all the incentive they need. Alone, Tao tries to contact the Shadowmaster but with no answer — he storm out. With the Nomads safe again for the moment, Arushka heads to the Mine where Noah has been captured by Jett. Quick thinking gets Noah and Arushka into the Beast trailer. Accessing the power source, Noah grabs Arushka's hand ad they white-out as a volatile Tao rips the door open. Where are they now?

Arushka now has the horses she wanted but Noah tells her he can't help her bring back more animals to Haven — he wants to go home. Bidding them farewell he heads off towards the Mine. On the way a brave and loyal Dolly saves him again and his journey must be abandoned. The Shadowmaster exerts his power. Tao must mine more Thunderstone! He orders Tao to leave Noah to him, he has a plan! The Nomads have made their way back to the Cavern, but unknown to them, lurking in the darkness, following and watching their every move is Ferris. The Triumvirate summon Noah's family and Dr. Pretorius to appear before them. The charge is one of unauthorised scientific experimentation. North Col's strict laws must be obeyed if they wish to remain part of the community. As the sun rises on a new day Noah wakes from a dream of a world full of animals. He forges a pact with Arushka — together they will save animals from past and bring them to the future, to Haven.
