Set in a world like ours but entirely inhabited by animals, Sing stars Buster Moon (Academy Award winner Matthew McConaughey), a dapper Koala who presides over a once-grand theater that has fallen on hard times. Buster is an eternal optimistokay, maybe a bit of a scoundrelwho 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.
Five lead contestants emerge: A mouse (Seth MacFarlane) who croons as smoothly as he cons, a timid teenage elephant (Tori Kelly) with an enormous case of stage fright, an overtaxed mother (Academy Award winner Reese Witherspoon) run ragged tending a litter of 25 piglets, a young gangster gorilla (Taron Egerton) looking to break free of his family's felonies, and a punk-rock porcupine (Scarlett Johansson) struggling to shed her arrogant boyfriend and go solo. Each animal arrives under Buster's marquee believing that this is their shot to change the course of their life.
