Serbian fashion designer Irena Dubrovna and American marine engineer Oliver Reed meet in Central Park, fall in love, and marry after a brief courtship; but Irena won't consummate the union for fear that she will turn into a panther compelled to kill her lover, pursuant to a belief harbored by her home village.
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.
