My Aunt, Your Aunt (1956)

Tommy is basically a nice guy, but he's got a criminal record and no money. Trying to get a little portering work at the railway station, he carries some bags for a couple of crooks, but the bags are stolen: they actually belong to Lola, a cabaret performer. Tommy finds out that the crooks are just out of prison and are planning a big bank robbery, and he decides to get in on the job, so as to expose them later. They need to rent a flat above the bank strong room, and the caretaker, (Hans Gippner) will only let it out to women. Luckily the stolen suitcases contain all of Lola's stage costumes, fortunately in sizes suitable for all three men. Back to the flat, and Gippner is taken in by the "women". The owners of the flat are two anthropologists who suddenly return from Africa and want their flat back: Gippner had no right to let it out. However the tense situation is defused when two of the crooks, still in drag, flirt with the two men and are invited out to dinner. Predictable slapstick ensues; but will Tommy turn over a new leaf and return to the straight and narrow?
