Ashes to Ashes is a British science fiction and police procedural drama television series, serving as the sequel to Life on Mars.
The series began airing on BBC One in February 2008. A second series began broadcasting in April 2009. A third and final series was broadcast from 2 April to 21 May 2010 on BBC One and BBC HD.
The series tells the fictional story of Alex Drake (played by Keeley Hawes), a female police officer in service with the London Metropolitan Police, who is shot in 2008, and inexplicably regains consciousness in 1981.
The first episode of the series reveals that, in the present day, Drake has been studying records of the events seen in Life on Mars. Upon waking in the past she is surprised to meet the returning characters of Gene Hunt (Philip Glenister), Ray Carling (Dean Andrews) and Chris Skelton (Marshall Lancaster) all of whom she has learned of from her research, the trio having transferred from the Manchester setting of Life on Mars (Manchester and Salford Police) to London.
