This year’s holiday season, Illumination Entertainment’s global hit animated film franchise begins a new chapter with bigger dreams and more hits. Buster Moon, an ambitious koala, and his all-star cast of animal artists are about to present the most dazzling stage show ever… in the dazzling entertainment capital of the world. But there’s a catch: They must first convince the world’s most reclusive rock star – voiced by music legend Bono in his animated debut – to join them. Buster (voiced by award-winning actor Matthew McConaughey) and his artists have transformed his new Moon Theater into the hottest performance venue in the area, but now he has bigger ambitions: to premiere a brand-new cabaret show at the glittering Cristo Tower Theater in Red Beach. With no showbiz connections to speak of, Buster and his crew of artists—including worried mother pig Rohitane (voiced by Reese Witherspoon), rocker porcupine Ash (voiced by Scarlett Johansson), hardworking gorilla Johnny (voiced by Taron Egerton), shy elephant Mina (voiced by Tori Kelly), and, of course, show-off piglet Gaunt (voiced by Nick Kroll)—must sneak into the offices of world-famous Kaunt Entertainment, owned and run by ruthless entertainment mogul and wolf Jimmy Kaunt (voiced by Emmy Award winner Bobby Canaver). Desperate to get Mr. Kaunt's attention, Gaunt suddenly has a flash of inspiration and gives Buster a super-funny idea, which Buster has no choice but to adopt: promise Mr. Kaunt that their new show will be headlined by legendary rock lion Corey Calloway (voiced by Bono). But the problem is, Buster has never met Corey, and the legendary rock singer retired from the music industry more than a decade ago after losing his beloved wife. He has lived in seclusion for more than a decade and no one has seen him since. As Gaunt is helping Buster design a unique stage show masterpiece, the pressure (and terrible threats) from Mr. Crystal are increasing. Buster embarks on a great adventure to find the legendary rock lion king Corey Calloway, hoping to convince him to return to the stage. What was originally just Buster's dream of becoming famous has turned into a modern fable, reminding everyone that the power of music is strong enough to heal the saddest broken heart.
