A sequel to the series, Ashes to Ashes, also referencing another David Bowie song, began airing on BBC One in February 2008, followed by a second series in 2009 and a third and final series in 2010.

Plot

Life on Mars tells the fictional story of Sam Tyler (John Simm), a policeman 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 2006. 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

 

Themes and storyline

After the premiere, each of the remaining fifteen episodes begins with a short teaser before a monologue in which Sam repeats, as part of the moving imagery of the title sequence:

My name is Sam Tyler. I had an accident and I woke up in 1973. Am I mad, in a coma, or back in time? Whatever's happened, it's like I've landed on a different planet. Now, maybe if I can work out the reason, I can get home.

This questioning is a central plot device throughout the series, displaying both the character's and the audience's uncertainty about what has happened.
Throughout the course of Life on Mars, Sam's uncertainty is reinforced by frequent paranormal phenomena, such as hearing voices and seeing images from 2006 on radios, telephones, and televisions. The voices discuss his medical condition, leading him to partially believe that he is in a coma. Other elements suggest to him that he is insane, such as his frequent and unexpected encounters with the Test Card Girl from Test Card F, who speaks directly to him. Annie Cartwright partially persuades Sam that he is truly in 1973, arguing that his mind would be unable to fabricate the amount of detail and tangibility in the world where he finds himself, evidence that he is in fact in 1973.
However, Sam's uncertain situation is not the focal point of most episodes, remaining a sub-plot. In most episodes, the main plot centres on a particular crime or case relating to the police, such as drug trafficking, a hostage situation, murders and robberies. For this reason, most episodes follow a conventional police drama format. As the series progresses, Sam focuses on how he will get home in almost every episode.
A recurring motif throughout the series is the overlapping of the past and present. For example, during Series 1: Episode 6 Sam hears the voice of his mother in 2006, telling him his life-support will be switched off at 2:00 pm. At the same time he is called into a hostage-taking situation, where the perpetrator states that he will kill his victims at precisely the same hour. Sam also encounters people whom he knows in the future as their younger selves, including suspects, friends, his own parents, and himself as a child.
Sam comes from a politically correct and scientifically advanced era, in which suspects' rights and the preservation of forensic evidence are stringently observed. His background leads Sam into conflict, as other characters exhibit openly sexist, homophobic, disablist and racist behaviour, and often indulge all these prejudices while carrying out their police duties.
The series frequently makes use of Gene Hunt's comical rudeness in the form of jokes and dramatic irony about a future which the audience already knows, but which the characters in 1973 do not. For example, in Series 1: Episode 5, Hunt declares, "There will never be a woman prime minister as long as I have a hole in my arse."
Another running joke in the show is Sam's confusion about police work in 1973, as he often mistakenly mentions techniques and technologies that were not used in 1973, such as two-way mirrors. One such running joke is that Sam continually gives criminals the updated version of the Right to Silence warning, which was changed in 1994. When he does so, someone around him usually points out that he is giving the warning incorrectly.

Finale

It is revealed in the final episode that Sam's coma had lasted so long because he had a tumour of the brain. Tyler comes to believe the tumour is embodied by Hunt, and begins to think that by bringing Hunt down, his own body can recover. To this end, Tyler begins to collaborate with Frank Morgan (Ralph Brown) to bring Hunt down. While Tyler and the team are engaged in a firefight with armed robbers, Sam returns to 2008. He eventually comes to realise that he has become used to, and enjoys, the 1970s, seeing it as his "real world". In an attempt to get back to 1973 to save Annie and the rest of the team from death, Sam leaps off of the roof of the police station, arriving back in 1973 and saving the team, promising never to leave them again. Writer Matthew Graham wrote the scene to indicate that Sam is now in the afterlife, but acknowledged that the ending is ambiguous and open to other interpretations, such as lead actor John Simm's belief that Sam may not have returned to the present. In the final scene, the team drive off, with Sam and Gene bickering as usual. Children run past, including the girl from Test Card F. She looks directly into the camera before reaching out and "switching off" the television the viewer is watching, signifying that the story has come to an end.
The first episode of sequel series Ashes to Ashes shows that DI Alex Drake of the Metropolitan Police has been studying Tyler's notes and 2008-era personnel file, in which his photograph is overstamped with the word "SUICIDE". Ashes to Ashes, which implies that Gene Hunt's world is in some sense real, states that Sam lived another seven years in that world, during which time he married Annie but had no children. Drake speculates that this happened while, in reality, he was in his dying moments, and fears that the same may be happening to her. As far as Hunt and his colleagues are concerned, Tyler apparently died in a car chase in 1980.
In the final episode of Ashes to Ashes it is revealed that the world of Life on Mars/Ashes to Ashes is in fact a purgatory for dead police officers. The Railway Arms pub seen throughout Life on Mars is shown to be the entry point to Heaven, and Gene Hunt mentions how he sent Sam in once he was ready.
