Meek clerk Arthur Price is desperately in love with the sweet Ann, the boss's daughter but is too shy to ask her out. By chance he meets charming if pushy Charlie Prince who is homeless and, in return for Arthur letting him move his large trunk into his lodgings and become his room-mate, Charlie gives him sound advice on wooing Ann with the result that the couple get engaged. Charlie has now outlived his usefulness and the newly confident Arthur has no qualms about getting rid of his mentor as he and Ann prepare to go away together. Will he get away with it?
