Four Parts (1934)

Mom lives with her four grown sons, identical quadruplets: Charley's a doctor, and the other three are a bus conductor, a traffic cop, and a taxi driver. Walking to work, Charley bumps into a young lady, they chat, and he tells her he'll see her again. Within minutes she thinks she's going crazy as she goes from bus to street, to cab, to doctor's office and encounters four men who look identical to the man she's just met. Charley straightens her out and invites her to meet the family that night: the boys are rehearsing for a musical number. Can she tell them apart long enough to flirt with the right one? And if she does, then what?
