In turn, Gorman uses his animals to kill these men. When a New York City zoo suggests a fundraising gala, Gorman sees a prime opportunity to dispatch the dashing Roger and anyone else who might cross him.

Un zoólogo, millonario, deportista y celoso hasta la locura utiliza los animales del zoológico para eliminar a los pseudo pretendientes y no tanto de su esposa. La primera víctima aparece con los labios sellados para que «no bese nunca más a otra mujer casada».
