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.

Animal rights activists have threatened a series of attacks in London and the first victim, the daughter of a commercial laboratory owner, is in hospital. Gene orders his team not to sleep until those responsible are behind bars.

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.

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.
