As the summit prize pot dwindles, trust will be tested as the mountain serves up a jaw dropping challenge. A massive fail leads to one hiker threatening to leave the competition as a secret chaser is released to hunt the group down.

14 hikers have started the adventure of a lifetime to reach The Summit in 14 days - but they're realising not all of them will make it. One hiker has fallen, and they don't have a million dollars anymore.

A chaser catches the hiking group with the intent to steal someone's cash and vote them off the mountain. There's a big price to pay with a dizzying challenge and a massive storm forces a dramatic evacuation.

In a thrilling game of survival, 14 Australians from all walks of life fight to haul one million dollars to the top of the mountain. With the cash stuffed in their backpacks, obstacles and gameplay will dictate who reaches the summit.

12 hikers are left on the mountain, and with only 11 days left to get to the summit and claim their cash prize, the group are realising that getting to the top is about a whole lot more than physical endurance.

In the quest to reach the summit in 15 days, the 13 remaining hikers are already struggling. A medical emergency shocks everyone, a terrifying rope crossing blocks their path and it all leads to a checkpoint where someone will be voted out.

The last 5 hikers begin their final climb to the summit, but ahead of them a terrifying obstacle could see them burning cash. A shock at the final checkpoint is nothing compared to the game changing twist to come.

An obstacle in the ice challenges the final hikers' nerves and with it comes a brutal sacrifice. An agonising decision then falls to one hiker alone; the ascent to the summit was never going to be easy.

The thrilling game of survival reaches its most emotionally charged day yet, as the hikers come face to face with their loved ones on a video call before being ordered to abandon one of their own at camp and sneak out in the dead of night.

The group learns about a chaser racing to catch them, so will need to step it up a gear if they want to avoid their cash being stolen. A terrifying obstacle stands in their way and two of the biggest competitors go head to head.

Jai Courtney sends 14 everyday Australians on the adventure of a lifetime: a pulse pounding trek to the top of a mountain with a million dollars cash stuffed in their backpacks.

In a brutal final blow, the final trekkers who make it to the top with their dreams of sharing almost half a million dollars are cut short, as the trekkers they cut from the mountain return to decide how the money is shared.
