Gary, Jacko, Charlie and Adam have completed their latest tour of duty in Afghanistan and arrive at the aircraft hangar ready to be taken home, only to be told their flight has already left. Faced with waiting another 12 hours in a hot, cramped hangar, Gary decides to try and bribe his way onto an earlier flight using a pretty uninspiring collection of belongings from the boys. He's been turned down by the RAF as well as most of the squaddies in the hangar until finally he meets Cammy, a squaddie with an impeccable sales pitch and an offer Gary mistakenly thinks is too good to be true.
