An island populated entirely by happy, flightless birds or almost entirely. In this paradise, Red, a bird with a temper problem, speedy Chuck, and the volatile Bomb 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.

Red, Chuck, Bomb and the rest of their feathered friends are surprised when a green pig suggests that they put aside their differences and unite to fight a common threat. Aggressive birds from an island covered in ice are planning to use an elaborate weapon to destroy the fowl and swine.
