Business elite Tom Brand (Kevin Spacey) is a complete workaholic, but often ignores family and family ties. On the birthday of his daughter Rebecca (Malina Weissman), he rushed to the pet store after being late for work and bought a cat she liked for his daughter. However, the pet store owner (Christopher Walken) used magic to trap his body in a pet cat. Tom, trapped in his pet cat, shouted for help, but it was just a "meowing" to humans who could not understand cat. At this time, Walken appeared in front of its cage and told it that he was a "cat whisperer", but Walken did not come to save him this time, but just made him think about the reason why he had been turned into a cat. The desperate Spacey exclaimed,"I hate cats," but learned that cats 'lives are very short and they are likely to be trapped here for the rest of their lives. The condition for returning to their original form is to be a competent husband and father. A series of ironic stories followed.
