Partners in Crime is a 1942 British short propaganda film directed and written by Sidney Gilliat and Frank Launder. It was produced for the Ministry of Information by Gainsborough Pictures. It delivers a reprimand to housewives meddling in the black market.
A burglar breaks into a house, and subsequently sells the stolen goods to a fence in a pub. Mrs Wilson buys black market meat from her butcher, and this transaction is portrayed as a parallel to that between the burglar and fence. The fence is arrested and tried before a judge. After the closing titles of the film the judge breaks the fourth wall and sternly addresses a warning the audience, which includes Mrs Wilson.
