After being hit by a car in 2006, Tyler awakens in 1973 to find himself working for a predecessor of the GMP, the Manchester and Salford Police, at the same station and location as in 2006.

After a near-fatal car accident, smart, savvy, sharp-suited detective Sam is mysteriously transported back to 1973 - only four years after he was born. Confused by his new and outdated surroundings, Sam impatiently tries to return to the present, but the police force of long ago needs his help.
