Illumination's latest animated adventure explores the emotional lives of our pets, the deep bond between them, the families that love them, and it answers the question: What are your pets really doing when you're not at home?

Terrier Max (Patton Oswalt) is coping with major life changes after Katie's marriage and the arrival of a toddler. Meanwhile, Gidget (Jenny Slate) tries to rescue Max's favorite toy from a cat-packed apartment with a little help from her feline friend Chloe (Lake Bell), who has discovered the joys of catnip. And Snowball (Kevin Hart) gets delusions of grandeur that he's a superhero after his owner starts dressing him in superhero pajamas. But when Daisy (Tiffany Haddish), a fearless Shih Tzu, shows up to ask for Snowball's help on a dangerous mission, he'll have to summon the courage to become the hero he's been pretending to be.

Can Max, Snowball, Gidget and the rest of the gang find the inner courage to face their biggest fears?
