Jai Courtney sends 14 Australians on the adventure of a lifetime; a trek to the top of a mountain with a million dollars cash stuffed in their backpacks and the mysterious Mountain's Keeper on their tail.

The 14 hikers continue an adventure to reach the summit in 14 days, but they are realizing not all of them will make it; one hiker has fallen, and their $1 million is removed from the prize pool.

Twelve hikers are left on the mountain with only 11 days left to get to the summit and claim their cash prize; the group start to realize that getting to the top is about more than just physical endurance.

The group falls a day behind; the remaining ten members have seven days to get to the summit with $785,000 left in the prize money on their backs.

Jans' taunting of the Mountain's Keeper propels the hikers into a terrifying run for their lives.

Sam's betrayal costs the group more than time and money; Jans finds a way into Brooke's heart; shifting loyalties force contestants to wonder who they can really trust.
