Garth Jennings writes and directs this animated musical comedy featuring the voices of Matthew McConaughey, Reese Witherspoon and Seth MacFarlane. When koala Buster Moon (McConaughey)'s theatre is condemned to closure due to lack of profit, he decides to host a singing competition to raise funds to keep it open. With news of the event soon causing a stir, most of the town decides to audition. Young gorilla Johnny (Taron Egerton) seizes his chance to escape the criminal life his gangster father is forcing him into and soon becomes a front runner for the title along with brash mouse Mike (MacFarlane), rock star porcupine Ash (Scarlett Johansson) and self-effacing pig Rosita (Witherspoon). With the futures of the theatre and the performers on the line, the unlikely gang do their best to put on a show that the town will never forget.
