Betty is startled awake in her bed on a stormy night. She searches for the cause of the shock while she sings the song. Then, unexplainable phenomena start happening in the house. Mysterious Mose (Bimbo) appears, and sings part of the song. Bizarre cartoon creatures appear and, at first, sing and enhance Moses mysterious image. Quickly, however, the antics become frightful even to Mose. The film escalates into chaos, which ends when Mose bursts, revealing him having been an automaton (full of cogs and springs) the whole time.
