During a celebration, the Chef of the nefarious Bergens kidnaps a number of Trolls, all with the aim of serving them to the Troll-hungry Bergens. It's up to Princess Poppy and the grumpy Branch to find their friends before they become a meal for the Bergens.
With the existence of several Troll tribes, each tribe has their own genre of music that they are dedicated to. Poppy and Branch set out to protect that diversification after they learn of the nefarious plot of the rock queen, who wants to take over the other tribes to make her genre reign supreme.
In the new edition of the adventure-comedy, Floyd is kidnapped, so Branch and Poppy decide to unite and gather the rest of the trolls in order to save Floyd at all costs.
