Life on Mars

In the British cop-centered sci-fi drama Life on Mars, Sam Tyler (John Simm) wakes up after a car wreck to find himself transported thirty years backward in time into the year 1973. Once in the past, he joins the police squad and starts working on a case that somehow seems related to the one he was working on in 2003 before the car accident. The show was later developed for American network TV, but the nudity in the UK original was left out, which might explain the Stateside version's early demise.
