Starring John Simm as Sam Tyler, an ambitious young detective who is determined to keep the streets of 21st Century Manchester safe. But after a near fatal car accident, Sam wakes up, dazed and confused, three decades earlier in 1973, struggling to understand what's real. Has he gone back in time? Is he in a coma? Or has he simply gone insane? What follows is Sam's 21st century account of 70s life feeling like a fish out of water. He must come to terms with an unfamiliar environment and an archaic CID unit where, using his modern know-how, he is integral to the unit's investigation process as he learns how to adapt to their old-fashioned technologies and etiquettes. Sam's new boss is hard-nosed DCI Gene Hunt (Philip Glenister - Vincent), who gets results by trusting his gut instinct and sheer brute force. Strangely the pair make a good team. This DVD boxset contains every episode from Life on Mars Series 1.
