When a new threat emerges that puts both Bird and Pig Island in danger, Red, Chuck, Bomb, and Mighty Eagle recruit Chuck's sister Silver and team up with pigs Leonard, his assistant Courtney, and techpig Garry to forge an unsteady truce and form an unlikely superteam to save their homes.
The movie takes us to an island populated entirely by happy, flightless birds – or almost entirely. In this paradise, Red (Jason Sudeikis, "We're the Millers", "Horrible Bosses"), a bird with a temper problem, speedy Chuck (Josh Gad in his first animated role since "Frozen"), and the volatile Bomb (Danny McBride, "This is the End", "Eastbound and Down") have always been outsiders. But when the island is visited by mysterious green piggies, it’s up to these unlikely outcasts to figure out what the pigs are up to.
