P.C. Litten recognises a photo of a wanted armed robber, but takes the information to D.I. Galloway instead of Sgt. Cryer, and gets into trouble with both men. Meanwhile, a gang of thugs is robbing local shopkeepers, and P.C. Edwards purses a mugger into a derelict building and is trapped when the floor collapses beneath him.

Roach and Dashwood arrest a man at an after match function. The suspect tries to help a girl and gets stabbed. Roach gets very little cooperation at another police station and has a run-in with the Inspector. The girl (Tulip) is a prostitute and they talk to her pimp to help look for her. They find her at the hospital when they go to pick up the suspect who turns out to have caused Tulip to miscarry.
