Max's life as a favorite pet is turned upside down, when his owner brings home a sloppy mongrel named Duke. They have to put their quarrels behind when they find out that an adorable white bunny named Snowball is building an army of abandoned pets determined to take revenge on all happy-owned pets and their owners. The film will feature an all-star team of comedians such as Louis C.K., Eric Stonestreet, Kevin Hart, Albert Brooks, Lake Bell and Ellie Kemper.
