Can Alex get back to the future?

Alex is 24 hours away from the event that changed her life - the murder of her parents in a car bomb - and she's sure that if she can save her parents, she'll get home to her daughter in 2008. Alex turns her parents' death into a 'case' - a crime that hasn't happened - and enlists Ray to help her in her mission.

Meanwhile, Gene is worried as Lord Scarman is due to visit the station. Desperate to make a good impression, Gene releases all the prisoners and locks up Chris so he can give the station a good review. Then Alex turns up with Tim and Caroline Price - her parents - after arresting them for possessing drugs and they're thrown in a cell.

The next morning, Gene lets Alex's parents go - but when Alex finds out that Arthur Layton has been released from prison, she knows there's no time to waste if she's going to stop the impending tragedy. As Alex and Gene race to where the bomb is set to go off, it seems everything's in place as it was 27 years ago.

But has Alex done enough to save her parents? And will she get back to 2008?
