The Life on Mars spin-off moves on a year when it returns to BBC One this Monday.
The second series takes the detective team from 1981 to 1982 where they are faced with corruption, deceit and increasing levels of crime.
Philip Glenister, who recently starred in ITV1's supernatural drama Demons, returns as DCI Hunt alongside DI Alex Drake, played by Keeley Hawes, who is still stuck in the 1980s.
Talking about what's in store for his character Glenister says in a statement: "In this series of Ashes to Ashes Gene is still out there being a maverick, but what I always say about him is that, while he bends the rules, he never breaks them."
"There is a police corruption theme running throughout the series so it does feel darker than series one," he continued; "the corruption breeds a lack of trust and coherence which is unbalancing for everybody."
The premiere of series two, which will also see the return of DS Ray Carling (Dean Andrews), DC Chris Skelton (Marshall Lancaster) and WPC Sharon Granger (Montserrat Lombard), kicks off with the introduction of a new character -- a legendary detective nicknamed 'Super Mac', played by V for Vendetta's Roger Allam.
The death of a policeman in a Soho strip club brings the team's new boss into the show, while Alex continues to receive flashbacks from the present.
Attracting 7 million viewers (29.1% of the total TV audience) to its first ever show, season one of Ashes to Ashes became an instant success. Despite losing viewers as the series progressed, the show remained a highlight of the BBC's drama schedule, bowing out with a respectable 5.4 million viewers (23% of the total TV audience).
The cop drama also went down well on TV.com, with the first series gaining an average TV.com score of 8.7. It has also described by fans as influential and classic.
Ashes to Ashes new eight-part series begins this Monday, April 20, at 9pm on BBC One.
