When a dead man is found in a Soho strip club, it looks like a sex game has gone wrong. So when the deceased is discovered to be a police officer, Gene and Alex are ordered to keep the case under wraps.

The team is on the hunt for major vehicle thief Jed Wicklow, but when a car chase leads to his death, Gene stands accused of causing it through reckless driving.

Alex is adamant that there was something wrong with Jed at the wheel and wants to prove that the crash wasn't Gene's fault. The deceased Jed was a Romany gypsy, and hostilities run high on the camp as CID heavy-handedly try to uncover the circumstances of his death. But in an investigation that's already met with resistance, someone in the police force also appears to be standing in their way.

A face from Gene's old stomping ground of Manchester shows up called Jackie Queen. Jackie is a reporter who is investigating teenagers who traveled to London from the north and have disappeared.

When a violent burglary occurs at Alex's in-laws' house, she comes face-to-face with their son Peter, the 14-year-old future father of Molly! Alex is desperate to help Molly's grandparents all she can, but Gene wants a big collar to bury the press stories of police corruption, and dismisses the case as trivial.

When the fingerprints from the crime scene reveal the burglar was George Staines, a notorious gangster, now supposedly dead, Gene realises this could be the catch he was after. Alex remembers hearing stories about the burglary, and is convinced that she would remember if the culprit was as infamous as Staines. Gene is determined to uncover the truth and get the headline he deserves.

Alex finally meets the mysterious man who has been leaving roses in her apartment and office. He tells her that she can go home to see her daughter again, but involves her becoming corrupt.

After a dead body is found in the canal it is identified as Colin Mitchell. Alex is certain that the dead man's wife Donna is not telling everything and she is determined to uncover the truth. Back in 2008, Alex has surgery to remove the bullet from her brain.

CID find a body buried in concrete as they investigate a drugs drop at a building site. Alex thinks she is getting better and will soon wake up in her own time. Working on the case though starts to clash with her wish to be back home.

After Alex catches an infection back in 2008, she knows the doctors think she wont pull through. Distance grows between Alex and Gene and their relationship is put under the greatest strain yet.
