Alex is 24 hours from the event that changed her life as a child – the murder of her parents by a car bomb. She believes that if she can save her parents, she will get home to her daughter in 2008. She makes her parents’ death into a case, but it's a crime that hasn’t happened yet.
Meanwhile, the station is in chaos following a Gay Pride demonstration and an inspection from Lord Scarman. To make matters worse, Alex turns up with her parents, Tim and Caroline Price, having arrested them for possession of drugs.
After they spend a night in the cells, Gene lets Alex’s parents go. When Alex finds out the man who shot her in 2008, Arthur Layton, has been released from prison, she knows there’s no time to waste if she’s going to save her parents.
