Ashes to Ashes is a British science fiction/police procedural drama television series, serving as a spin-off from the original series, Life on Mars.
The transmission dates given below refer to the original UK broadcast on BBC One.
The first series of Ashes to Ashes shows a 21st-century police officer, Detective Inspector Alex Drake (Keeley Hawes) investigating the notes Sam Tyler (John Simm) wrote. While in the process of this, Drake is shot and awakes in 1981, where she meets Gene Hunt (Philip Glenister), Ray Carling (Dean Andrews) and Chris Skelton (Marshall Lancaster) whom she has read about in Tyler's notes.
The second series was confirmed to be in production in early 2008. This series takes place in 1982, and is the fourth British series overall in the Life On Mars franchise.
Series 3 consists of eight 60-minute episodes. The first episode of the series aired on 2 April 2010. Episodes 7 and 8 were joined as the show's first "two-parter" (i.e. the two episodes form one direct narrative) and was advertised as such.
A brutal gang murder leads the team to investigate a Europe-wide jewel smuggling ring. Keats completes his report on the department and tries to turn the team against Hunt and transfer them to his control, revealing his true colours. Alex goes to investigate a house in Lancashire which she believes holds the secret of Sam Tyler's disappearance. She uncovers a body in a field, and its warrant card reveals that it is a young Gene Hunt (and its ghost is the young PC haunting her). Meanwhile, Chris, Ray and Shaz are given videos by Keats, which show them that they too are police officers who died in tragic circumstances.
