9-year-old alien Gark is on a mission to save the universe. When he is sent to Earth for training, Gark meets vain housecat Max, who the alien mistakes for a tiger that can teach him how to be a hero. Max, however, doesn't know a lot about bravery, but he does know a lot about activities like knitting and watching TV. Gark's adventurous tendencies force anxious Max to start acting like the tiger that Gark suspects he is in order to help the alien, who has uncontrollable superpowers, fulfill his destiny of saving the world.
