In a world of anthropomorphic animals, koala Buster Moon owns a theater, having been interested in show business since his father took him to his first music show as a child. Following financial problems brought up by the bank representative Judith, he tells his wealthy friend Eddie that he will host a singing competition with a prize of $1,000. But Buster's assistant, Miss Crawly, accidentally appends two extra zeroes, and the promotional fliers showing $100,000 are blown out of Buster's office into the city streets.
