P.C. Muswell and P.C. Lyttleton are on the lookout for a lorry full of stolen woolen coats. Ch. Supt. Brownlow is throwing a farewell party for his retiring clerk. D.I. Roy Galloway questions D.S. Burnside when he gatecrashes the party, and Burnside admits that he fancies June Ackland. D.C. Mike Dashwood realises the scotch being poured at the bar has been stolen, and Galloway asks Ackland to keep the remaining bottles aside as evidence. Despite warnings from the D.I. and the Chief Super, D.S. Ted Roach drives home extremely drunk and crashes his car into a fence. Knowing he'll be sacked if he's found out, Roach sleeps on a friend's boat overnight while he sobers up, but spots the coat thieves on the docks when he awakens, and the men are arrested when they are found stuck in a freezer. Roach also sweet-talks the man whose garden he crashed into by offering to get him into the Special Constabulary. P.C. Reg Hollis grasses on Roach to Brownlow, in the hope of getting the clerk's job.
