The animated movie is based on the famous mobile app game of the same name and has a little plot on its own.
Bird island is a tranquil place which is inhabited by flightless birds. Red (voiced by Jason Sudeikis) resides outside the village as he is grumpy and has anger issues. He is sentenced to anger management classes where he comes across Chuck, Terence and Bomb.
Meanwhile, pigs land on the island and try to act as friends. They charm the leader of the birds and convince the others that they are well-wishers. The whole village gets carried away with the pigs' antics while Red alone stays suspicious. Along with Chuck and Bomb, Red tries to get the help of the Mighty Eagle (voiced by Peter Dinklage) who is said to be the protector of the island.
Will Red, Chuck and Bomb convince the Mighty Eagle? What is the real plan of the pigs and do they succeed? All these questions are answered in the rest of the story.
The movie is light and doesn't leave a mark. The screenplay is weak and lacks wit. The final bombing scenes in the pig kingdom is enjoyable. Directors Clay Kaytis and Fergal Reilly has given a movie that lacks depth.
