Harry is a zealous traffic warden, whose eccentric hobbies of collecting stuffed birds and folk dancing cause great friction between him and his wife. Bad-tempered Gran's constant criticism of Harry does not improve matters. Also Harry's daughter, Ruby, is engaged to weedy Gerald who finds he has an allergy to the birds. However, Harry's hobby seemingly pays off when he returns home with an owl which is stuffed with hundreds of pounds. But when Inspector Travers of the C.I.D. arrives, Harry discovers he has been freely spending stolen money and is taken away to the police station.
