Cats are actually aliens. They come from planet Meow, and those of them that exist on earth are actually there to colonize the planet, but they have been lulled into inaction by human love and food. And so a Meowian warrior, Pudding, is sent to earth with a magical weapon, to galvanize the troops and initiate a global takeover. Except that upon landing, Pudding loses the weapon and undergoes a transformation, due to the earth’s atmosphere, from alpha-feline warrior to chubby, oversized cat, while a mix-up leads to him being adopted by a family. The father (Louis Koo), is a well-meaning but hopelessly childish ex-football star, the mother (Ma Li) an highly-strung aspiring actress, the son (Andy Huang) a wannabe-film director who for know mainly collaborates with his pets, and the daughter (Liu Chutian) suffers from a bad leg which keeps her away from the sporting activity she would like to join in. At first, Pudding – now renamed Xixili – plans to break up the family, but soon he is won over by their kindness.
