This animated comedy from Illumination Entertainment asks the question: what do our pets do all day when we're not home? For the critters living in a Manhattan apartment building, the answer is: whatever they want! A terrier named Max (voice of Louis C.K.) regularly invites his friends to hang out at his place while his owner (Ellie Kemper) is gone, but his quiet life is upended when said owner also takes in Duke (Eric Stonestreet), a stray mutt whom Max instantly dislikes. Their feud eventually causes both of them to get lost in New York City, and as they work together to find their way home, they cross paths with a vicious bunny (Kevin Hart) who plans to lead a group of abandoned pets on a mission of revenge against humanity.
