Liz Teasdale is having an affair with cabaret entertainer Tony Sorbo. Her husband, surgeon Philip Teasdale, has employed sleazy private investigator Felix Carstairs to tail them. As Sorbo and his wife Zita are performing their mindreading act at a hotel, Teasdale substitutes drugs for Sorbo's anti-smoking pills. Sorbo suffers a heart attack and is taken to hospital where Teasdale prepares to operate. The unexpected requirement to give a lecture to an audience of student nurses foils his plan to kill Sorbo on the operating table. Carstairs tells Zita what has been going on, and to cover his tracks Teasdale kills Carstairs. He prepares to perform a second operation on Sorbo, but this time Zita, Liz and the police are watching.
