A white cat named Victoria is abandoned by her owners in the streets of London. There, she meets a group of stray cats who take her to a colony of strays called the “Jellicles” where they teach her to adapt to her new environment. On the same night, the Jellicles are preparing for an event that is held every year known as the Jellicle ball where the leader, named Old Deuteronomy will select one cat to go to the heavy side layer and be reborn in a new jellicle life. But one cat named Macavity is out to get rid of the competition to be the only one standing to be reborn as the new jellicle leader with an iron paw.
