Branch (Justin Timberlake) and Poppy (Anna Kendrick) stumble upon a unique secret: six tribes of trolls, each practicing different styles of music, live all across the world. It is then up to the duo to unite and protect the other kingdoms of trolls when their musical styles are threatened by King Thrash (Ozzy Osbourne) and Queen Barb (Rachel Bloom). Co-directed by Walt Dohrn and David P. Smith, the film co-stars James Corden, Mary J. Blige, and Kelly Clarkson.
