Buster and his new cast are now focusing on the debut of a new play at the Crystal Tower Theater in the glamorous city of Redshore City. But with no connection, he and his singers have to make their way to the offices of Crystal Entertainment, run by ruthless wolf mogul Jimmy Crystal, where the band makes a funny impression of the role of lion rock legend Clay Calloway in their show. Buster must begin his search for the now-isolated Clay and persuade him to return to the stage.

Buster Moon and his friends must convince lonely rock star Clay Calloway to join them at the opening of the new show.
