Join the staff at the world's biggest primate sanctuary for joy and drama as they rehabilitate a host of cheeky monkeys.

Mexican monkey Bryan meets his chimp foster mum Sally, but no one is sure if he has been around another chimpanzee before. How will he react to his new mother? Elsewhere, Jim comes to the aid of lovable primate Charlie, who is being picked on by the other males in his group, especially at meal times. And the park faces an irreplaceable loss. Jim Cronin, has sadly passed away after a short battle with cancer. Will Alison and the team manage to keep his legacy alive?

Aris is still poorly; the baby woolly monkey finally gets a name; and the alpha male chimps exert their authority. But could there be a coup brewing?

The Chilean capuchins finally arrive in the UK, and there is bad news in the orang-utan house. Something has gone seriously wrong for Aris since his knee operation.

Orang-utan Aris needs surgery as his knee injury is worse than expected. Chimp Patricia finally relaxes in the company of alpha male, Hananya. And chimpanzee Seamus is in for a shock when he meets big male, Paco.

It is a big day for one of the park’s naughtiest residents, chimpanzee Seamus. He is moving from the chimp nursery into the bachelor pad. Toddler orang-utan Aris is in recovery, and one of his new housemates has decided to pick a fight with him. And what happens when Seamus meets his former partner in crime, Carli?

It is a vet day at the park, as John Lewis checks up on the leg that chimp Jimmy nearly lost. Baby chimp Rodders, meanwhile, must have a tooth removed after sustaining an injury during a play session; and there is a serious problem with the park’s biggest-ever rescue mission.

Seamus’ brief period of calm comes to an abrupt end. Elsewhere, chimp Susie takes her new baby outside for the first time; and there are problems with the travel arrangements for the Chile trip.

The new baby woolly monkey meets its own kind for the very first time. There is some growing up to be done as orang-utan Aris graduates from the nursery and meets Gordon. And there is a surprise in the chimp nursery as the cheeky Seamus seems to have learned to control his wild side.

Work begins on the new gibbon rescue centre in Vietnam – and not a moment too soon, as the first primates are already arriving to begin their rehabilitation. Back on home soil, there is the patter of tiny feet in Paddy’s chimpanzee group, while members of the bachelor chimp group fall out once again.

This special edition travels to Vietnam, where Monkey World is embarking on an exciting new project – its first foreign sanctuary for endangered primates. A new gibbon rescue centre is being built to protect these rare animals for the future.

The Nursery chimps get the better of Animal Manager Jeremy, but he has his revenge! We also meet chimpanzee Paddy, who’s been the perfect leader of his group for more than 15 years. And we find out why new alpha male Hananya is struggling with life at the top. There’s tension when a baby Woolly Monkey is born, but instead of being tucked up with mum, it’s been rejected. Will the endangered primate survive without human intervention?

Nerves run high as the team attempts a first at the park: a surrogate mum for a newborn baby orang-utan. The orang-utan nursery mob love spending time in their new outside enclosure, and stubborn Hsiao-Ning is even starting to enjoy life! And in Hananya’s group, Patricia is being pursued by the alpha male.

New recruit Koko, a stump-tailed macaque, meets her first companion in years: old boy Gerald. Dinda is about to embark on a new life with her orang-utan family, and we meet Gismo, a capuchin with a tragic past. And there is great excitement when golden-cheeked gibbons Peanut and Pung-Yo welcome a new arrival to their family.

Jim and Alison are on a special mission to Cancun in Mexico. They have travelled 5,000 miles to collect a lively three-year-old chimp called Bryan, who has been mistreated by his owner and needs a home with his own kind. Jim and Alison must prepare Bryan for the long and difficult journey back to Dorset. Meanwhile, Alison is frustrated in her efforts to rescue an adult chimp named Coco, who belongs to the same owner.

Tough love ensures that chimpanzee Bryan learns a painful lesson when he goes outside for the first time. Will woolly monkey Julio be brave enough to take his first steps outdoors? And, in Paddy’s chimp group, Lee gets hands-on with Susie. Could she be pregnant for the second time?

This special edition travels to Chile, South America, where the team has joined forces with the military to fly 88 Capuchin monkeys to Monkey World. It will be the park’s biggest and most challenging rescue ever. And for the four capuchins already living at the park, they have no idea that their lives will soon change forever.

Alison rescues Ruby, a marmoset with attitude and a bit of a weight issue. She has been well cared for but this free ranging marmoset needs company of her own kind. Back at the park there’s a group of primates who’ve had a weight problem in the past, but life is now blossoming for the residents at the stumpie house. Orphan orangutan babies Rieke and Bulu Mata discover the ups and downs of life in the nursery and after some renovations at Hananya’s chimpanzee enclosure, its young Thelma who leads the way.

The primate care staff suspect golden-cheeked gibbon Kim is about to give birth but after several hours and no change in her condition the vet is called in. It’s a tense time when Kim has to undergo an emergency cesarean. Aging saki monkey Jethro gets a surprise when new companion Chloe arrives from France but it seems Jethro isn’t the romantic type. At Levar’s woolly monkey enclosure there are treats on offer, pine cones packed with raisins, nuts and seeds and its all gone nuts in Franco’s capuchin group.

There's concern for elderly saki monkey Jethro, who needs surgery on his tail. Hot potatoes are served up with soup as the chimps get a winter warmer to start the day.

We catch up with Carli and Gypsy, the two newest chimp hooligans who have joined the boisterous bachelor group. Jim and Alison are on a rescue mission to Hungary to collect stump-tailed macaque Koko. She has been living in a pet-shop cage for 20 years and the team gets a feisty greeting.

There is a challenge for the staff as four chimps ‘move house’ on one day in the park’s biggest move around yet. Baby chimps Ash and Rodders have breakfast at home with keepers Emma and Paul. And, as Monkey World is the European crèche for baby orang-utans who need a home, there is news from Russia of an orang-utan orphan who needs a family.
