Plot

A bus transporting criminals from court to prison is held up by crooks who rescue one of their gang. The bus is driven to a deserted farm and the other occupants of the bus are locked in a barn. To give the gang leader plenty of time to escape, he tells everyone – two prison officers, the driver and five prisoners – that the barn has been doused in petrol, and that two gang members will stay behind outside to guard it, and will set fire to the straw-filled building if anyone tries to escape. The prisoners and officers start to interact, but soon find they may be in danger from yet another source.
