Illumination's smash hit returns with bigger dreams and spectacular songs as can-do koala Buster Moon and his all-star cast of animal performers launch their most dazzling stage extravaganza yet. There's just one hitch: first they have to persuade the worlds most reclusive rockstar, voiced by legendary music icon Bono, to join them.
Buster and his cast have turned the New Moon Theatre into a local hit, but Buster has his eyes on a bigger prize: debuting a new show at the Crystal Tower Theatre in glamorous Redshore City. But with no connections, Buster and his cast - including harried mother pig Rosita, rocker porcupine Ash, earnest gorilla Johnny, shy elephant Meena, and, of course, porcine provocateur extraordinaire Gunter - are forced to make a desperate bid and promise that their new show will star lion rock legend Clay Calloway. Problem is, Buster has never met Clay, an artist who shut himself away from the world more than a decade ago after the loss of his wife and hasn't been seen since.
Now, Buster must embark on a quest to find Clay and persuade him to return to the stage. What begins as Buster's dream of an out-of-this-world theatrical masterpiece becomes an emotional reminder of the power of music to heal even the most broken heart.
