Simone Simon ("Irina Dubrovna") comes to work in New York where she falls in love with Kent Smith ("Oliver Reed"). Their relationship soon becomes strained after she struggles with intimacy - you see she believes that should she ever even kiss someone she loved, she would turn into a violent feline and claw him to death. She confides in her now husband and somewhat sceptical, he sends her to a psychiatrist, the debonaire Tom Conway ("Dr. Judd"). Our story tracks her determination to get past this obsession in the face of her growing suspicion that "Oliver" is seeking solace elsewhere - and that they are planning on having her committed - in a tense and eerie way. The dialogue is quite stilted and the theatricality of the performances rob the film of much of it's pace - but it is still a good horror thriller.
