Desperate to improve his luck with women, London schoolteacher Colin (Michael Crawford) enlists his artist roommate, Tom (Donal Donnelly), to help drag a brass bed back to their flat. Along the way they meet Nancy (Rita Tushingham), a new girl in town, who follows them home. There they encounter Tolen (Ray Brooks), the third roommate and a consummate lady-killer. He tries to help Colin seduce Nancy, but ends up whisking her away on his motorcycle instead, and Colin is determined to get her back.
