On a tropical island inhabited only by flightless birds, Red (Jason Sudeikis) stands out in more ways than one. The entire island lives in relative comfort and perfect harmony. The few malcontents are sentenced to mandatory anger management classes, led by the nauseatingly perky Matilda (Maya Rudolph). While delivering a cake to a chicks birthday party, Red arrives late and can’t control his temper when the recipient refuses to pay for the order, due to Red’s tardiness. The altercation lands Red in anger management class. This is where we meet other characters like Chuck (Josh Gad) a mischievous yellow speedster. Bomb, a round black bird with a short fuse who, when angered physically explodes. Lastly there’s Terence (Sean Penn). Terence is the same type of bird as Red (apparently unrelated), but many times larger and only speaks with a short grunt or a long grunt. No one knows of the horrors committed to land Terence in anger management and it’s probably best that it remains that way. One fateful day the island is visited by its first visitors ever: a ship full of wayward pigs from Piggy Island. The Birds welcome their new friends into the flock, except for the skeptical Red, who questions the omelette loving visitors’ goodwill.
The affable Brad Whitaker (Will Ferrell) trying to make the best of a tough situation. Due to a mishap of great improbability, Brad is impotent and thus, unable to start a family of his own. So, if Brad can’t be the best dad ever; he’ll strive to be the best step-dad ever and that’ll take winning over Megan (Scarlett Estevez) and Dylan (Owen Vaccaro), the children of Sara (Linda Cardinelli) from a previous marriage and Brad’s current wife. As Brad makes small gains with the kids, his progress is grounded as Sara’s ex-husband Dusty Mayron, (Mark Wahlberg) announces his return. The polar opposite of Brad, a mild-mannered radio executive for a smooth jazz station; Dusty breezes in with a John Wayne swagger, turning Brad’s childish insecurities into an inferiority complex, in the time it takes Dusty to reach the bottom of the airport’s escalator. Since Brad can’t compete physically with Dusty, he’ll have to work smart to stop Dusty from taking over his marriage and kids’ affection.
