A team of expert engineers are abandoned in Arctic conditions in a simulated crash site, with the leftovers of a light aircraft and two snow mobiles. Their only chance of escape is to create a vehicle from the wreckage. Ex-Special Forces soldier and survival expert Ant Middleton oversees the team of three men and two women, who each bring a specific skill to the team - from aircraft mechanics to vehicle engineering. But as the freezing conditions close in, debilitating the group, the engineers are unable to agree on what to construct, and increasingly escape looks unlikely.
