Life on Mars tells the fictional story of Sam Tyler (John Simm), a male police officer in service with the Greater Manchester Police. After being hit by a car in 2006, Tyler awakes in 1973 and finds himself working for the predecessor of the GMP, the Manchester and Salford Police at the same station and location as in 2008. Early on in the series, it becomes apparent to Tyler that he awakes as a Detective Inspector, one rank lower than his 2006 rank of Detective Chief Inspector. As part of the Criminal Investigation Department, Tyler finds himself working under the command of Gene Hunt (Philip Glenister). Throughout the two series, the central plot centres on the ambiguity concerning Tyler's predicament of it being unclear to both the audience and the character whether he has died, gone mad, is in a coma or has actually travelled back in time.
