Struck by a passing car in modern-day Manchester, detective Sam Tyler wakes up in 1973, where he's the newest member of his old police squad. Sam's respect for proper procedure and 21st-century mentality clash mightily with his bullying boss, DCI Gene Hunt. Still, Sam adapts to crime solving in this retro world, despite hearing strange voices that call him back to his former life. When he bonds with sympathetic policewoman Annie Cartwright, will he still want to go back? Includes featurettes.
