When ex-SAS soldier, Michael Purdy, comes in front of the judge for hacking the bank belonging to the Minister for Invalidity Benefits and wiping out his personal wealth, he braces himself for a prison sentence.
What Michael doesn't expect, is to be put in charge of a group of offenders and sent to a remote location in the Sierra Nevada Mountains in Spain to teach them survival skills as part of their rehabilitation programme.
But Michael knows nothing at all about survival skills. He was sort of in the SAS, yes, but his shining record on the "Escape and Evasion" courses was more a testament to his computer skills than his ability to catch wildlife and barbecue it over an impromptu fire. Basically, he was the SAS's techy nerd and only achieved that position as a result of a bet with a fellow hacker.
Facing a stark choice between starvation or returning home to serve out their sentences, the group of offenders under Michael's supervision soon realise that the only way to survive is to use their own unique set of skills – the kind of skills that got them arrested in the first place.
