Molly’s daughter Lily partakes in some risqué online activity, which Freddie manipulates in an act of revenge against Molly. Meanwhile, Molly’s suspicions about Freddie’s involvement in Dorothy Moxley’s murder deepen.

Freddie puts Lily’s life in peril and Molly must race to save her as Freddie unravels. Meanwhile, Constable Freya Harris has been working on a tip-off that Gareth and Councillor Jacinta Clunes may be involved in some dodgy dealings.

Blood samples found on Councillor Jacinta Clunes’s car reveal a familial link to Dorothy Moxley. Alex brings Inspector Lewis to Grace’s house to show him the bones he discovered and learns that Lewis knows more than he’s letting on.

The investigation comes to a head as Gareth takes Molly hostage at knifepoint and Alex is captured by William and the Crofters.
