Life is easy on the peaceful Bird Island; however, Red--the flightless, bad-tempered pariah--finds it extremely difficult to keep his temper under control. Inevitably, his temperament will soon lead Red to a mandatory anger management class, where other outcasts, such as Chuck and Bomb, become the closest thing he'll find to family. However, nothing could get more on Red's nerves than a ship crammed with Captain Leonard's green-hued pigs who claim to come in peace. In the end, is there more to this friendly invasion than meets the eye? Will the cranky islander get to the bottom of this?

After saving Bird Island from an all-out green-pig invasion in Angry Birds (2016), the isle's always cranky local hero, Red, still finds himself doing battle with Pig Island. As the prank war between pigs and birds is raging, massive icy projectiles coming from the feathery tyrant Zeta's ice-capped Eagle Island threaten the security of both havens, unless Red and King Leonard agree to form a difficult but honest truce. Now, Red, Bomb, Mighty Eagle, Chuck, and his brilliant sister, Silver, have to join forces with Leonard's mighty porcine team to thwart the megalomaniac Zeta's bold schemes for world domination. However, is Red capable of change?
