Set in a world like ours but entirely inhabited by animals, Sing stars Buster Moon, a dapper Koala who presides over a once-grand theater that has fallen on hard times. Buster is an eternal optimist-okay, maybe a bit of a scoundrel-who loves his theater above all and will do anything to preserve it. Now facing the crumbling of his life's ambition, he has one final chance to restore his fading jewel to its former glory by producing the world's greatest singing competition.

Can-do koala Buster Moon and his all-star cast of animal performers prepare to launch a dazzling stage extravaganza in the glittering entertainment capital of the world. There's just one hitch -- he has to find and persuade the world's most reclusive rock star to join them. What begins as Buster's dream of big-time success soon becomes an emotional reminder of the power of music to heal even the most broken heart.
