Beneath the gay billows of the big-top seethes a veritable stewpot of illicit romance, false friends, rivalry and murder in this crime drama that contains the feature film debut of distinguished character actor Herbert Lom who plays a recently hired hypnotist who falls in love with a female trapeze artist, whose jealous partner is the brother of the circus owner. Desperately wanting the woman for himself, the new fellow mesmerizes the girl and suggests that she drop her partner during the next performance. She does, but the wicked hypnotist gets his comeuppance at the end.
