Trolls believe in the power of a hug, song and dance.
The happiest Troll of them all is Poppy (Anna Kendrick) and the un-happiest Troll is Branch (Justin Timberlake).
Branch feels the Trolls are unprepared for the Bergens, giant monsters that eat Trolls.
When the Bergens kidnap all of Poppies friends, she has to convince Branch to help save her friends in a hair-raising
adventure where everyone will show their true colors!
