Life on Mars
Sam is your quintessential modern copper, doing everything by the book and believing that his gut instinct shouldn't have a place in modern police work. This therefore sets up nicely the culture shock Sam experiences when he walks into Gene Hunt's world, courtesy of a traffic accident, where finger-prints take weeks to come back, blood-typing alone identifies suspects and the quickest way to get an arrest is to lean on a suspect until they squeal.
Sam doesn't know if he's mad, back in time or in a coma. Certainly most of his colleagues think he's a lunatic and Sam's not quite sure whether he's in a position to contradict them.
