Buster Moon is an elegant koala who runs a great theater that was once famous but has now fallen into disuse. Buster is an eternal optimist, a little grumpy, who loves his precious theater above all else and would do anything to save it. It was then that he found a golden chance to restore his image while avoiding the destruction of his dreams and all his ambitions: a global singing competition. Five candidates are selected for this challenge: A mouse as attractive as it is dishonest, a shy young elephant devoured by stage fright, a mother sow overwhelmed by its 25 young pigs, a delinquent young gorilla who only seeks to escape his family, and an epic punk pig who struggles to shake off her oversized ego boyfriend for a solo career. All these little people are going to come on Buster’s stage looking for the opportunity that can change their lives forever.
