DI Gabriel has just returned to work after being shot on an undercover job. He leads the police investigation of murdered drug baron Harvey Wratten and finds himself in a race with drug dealers eager to know who killed their boss.

The driver of Wratten's car is identified and both Gabriel and Joseph Bede are desperate to get to him first, but they find themselves in a three horse race with a shadowy figure that always seems to be one step ahead of them.

Bede reluctantly finds himself in the driver's seat for a drug deal. Meanwhile Gabriel continues to investigate the Wratten murder against his superior's instructions, and Honey discovers a secret.

Jay Wratten's insistence that Bob Harris is responsible for his uncle's murder causes problems for Bede's new business deal. Meanwhile, Gabriel struggles to placate his ex-mistress, and Gatehouse shows he'll go to great lengths to find Glickman.

Gatehouse finally finds Glickman with explosive consequences, Gabriel gets closer to finding out why he was shot, and there's help for Bede's floundering business deal from an unexpected direction.

Gabriel unearths some dark truths about Counterpoint which implicate his colleagues. Glickman warns that Gatehouse will hunt him down, and Bede gets one step closer to finally getting out of the drugs game.
