Stephen Tompkinson returns as Detective Chief Inspector Alan Banks in three more gripping crime stories.

Will Detective Chief Inspector Alan Banks and Detective Sergeant Annie Cabbot ever get their relationship together? Or will three wrenching crimes and the investigation of Detective Investigator Helen Morton keep them forever out of sync? Welcome back to the hit crime series set in a bucolic Yorkshire town, where you would never expect social workers to abduct a young boy ... never imagine finding a murdered journalist in a holiday chalet ... never...

Banks and the team begin the painful job of finding out exactly who was responsible for the tragedy that has changed all their lives forever, while dealing with the grief it has caused.

DCI Banks receives a disturbing phone message from estranged brother Roy and heads to Harrogate to find him. Meanwhile at a murder scene, the team is introduced to new recruit Helen Morton, who quickly alienates her colleagues with her tactless style. The officer then makes matters worse when she finds evidence linking Banks to the victim's body and speculates he could be a suspect.
