NYPD Detective Sam Tyler (Jason O'Mara) finds himself in the cultural hotbed of New York City in the tumultuous times of the Vietnam War, Watergate, women's lib and the civil and gay rights movements - without a cell phone, computer, PDA or MP3 player -- suddenly hurtled back in time when he's ripped from 2008 after being hit by a car while chasing down a criminal. He's trying mightily to understand what has just happened to him and how he can get back "home."

Just how will Sam deal with all this ambiguity while trying to remain a top detective, as he desperately attempts to get back to 2008? He might just find things aren't so dissimilar in New York circa 1973 and 2008.
