 He s tough, he s bald, he s British, and he s the guy police departments across America call when they have a new threat to tackle. This is Paul Castle, whose unorthodox training techniques - including everything from humor to humiliation - prepare local police officers for dangerous work. Paul goes to a new police department to help officers with a special challenge, whether it s bringing down meth dealers or kidnappers. Viewers will see how the officers change under Paul s tutelage - especially the weakest one, who will be profiled - and then watch the cops handle a highly realistic mock mission, or possibly a real raid.
