Simone Simon, portraying Irina Dubrovna, finds herself working in New York City and develops feelings for Kent Smith’s character, Oliver Reed. The connection between them experiences difficulties as she wrestles with emotional closeness; her belief is that any kiss from someone she cares about would trigger a transformation into a ferocious cat, leading her to attack the person she loves. Sharing this fear with her husband, who finds it hard to accept, results in him suggesting she consult a psychiatrist, the sophisticated Tom Conway, playing Dr. Judd. The narrative follows her efforts to overcome this anxiety while simultaneously growing concerned that Oliver might be looking for comfort elsewhere and potentially scheming to have her institutionalized—a situation conveyed through an atmosphere of suspense and unease. While the conversations feel somewhat unnatural and the actors’ performances lean toward a stagey quality, which slows down the film's momentum, it remains a worthwhile horror thriller.
