The murder of a football fan results in a clash of methods as Sam and Gene go undercover in a local pub to solve the crime. As Gene looks like he's set to drink the pub dry, Sam worries about their chances of finding the killer before Saturday's big match. And his relationship with the young son of the murdered man brings Sam's memories of his own father flooding back.

The death in custody of drug dealer Billy Kemble pits Sam against CID as he tries to uncover the truth. Sam demands a transparent investigation into Billy's death to encourage public trust in the police. When the evidence of what happened to Billy falls into his hands, Sam has a huge decision to make, which could either tear the team apart or find him an opportunity to get home.
