The Sweeney

A security guard is murdered during a payroll snatch. The local police force under Chief Superintendent Canning have no luck in catching the robbers and Canning is reluctant to work with Regan when the Sweeney are called in, frequently clashing with him. When Regan apprehends all the gang without telling him, Canning is far from happy. Regan is accused of corruption nine years earlier and Canning, his contemporary, refuses to help him. Fortunately Carter finds someone who will, but the whole experience leaves Regan extremely bitter.

After Regan gets a tip about an upcoming robbery from a trusted informant, the gang kidnaps his daughter to blackmail him into inaction.

Regan is staking out vicious robber Vic Tolman and his girl-friend Lyn Hurst, who have stolen the wages from the firm where Lyn worked. A surveillance is in progress on the flat belonging to Lyn's sister Joan, who is looking after her daughter. Regan and Carter eventually break into the flat and use the two women as bait for Tolman. He turns up but things do not go as planned.
