Rachel’s first case as sergeant is not exactly an easy one as she has to lead the team as they look into a high-profile missing person’s investigation from 23 years ago, after the body of a woman is discovered in a quarry. As Rachel sifts through swathes of police reports from years back and talks once again to the dead woman’s relatives, matters are made far worse by the fact that Rob’s dad Frankie was the senior investigating officer on the original case and it swiftly becomes clear that his incompetence marred the investigation, and now the press want answers.

Meanwhile, Janet tells Rachel that the sergeant’s job wasn’t right for her at the moment because Elise moving out has caused disruption in the family, but Janet also drops another bombshell when she announces that she’s looking for love and is trying out internet dating.
