Hitman Rob Shaw travels to a remote location after a distress call from his ex-wife. Upon arrival, he is met by his estranged father Jim, an ex-director of the Ministry of Defence, his ex-wife, her new husband and Rob’s two young daughters. Jim explains that a global nuclear event is imminent and invites Rob to join them in a bunker beneath the house. Rob rejects the invitation and attempts to leave just as the bombs begin to fall - he has no place or purpose in this new reality. However, when an anarchic gang of ex-soldiers take control of the bunker, his skills and dangerous mindset become the very thing the family needs.

Selection for the SAS is one of the world's toughest job interviews and physical fitness is only the starting point. What's really being tested is psychological resilience and character as candidates undergo sleep deprivation, interrogation and a series of increasingly complex mind games. In this programme, five ex-special forces soldiers re-create tasks from the SAS's secret selection process, putting 30 civilian men through the ultimate test of their physical and - more importantly - their psychological resilience.
