Set after Trolls:Band Together, Branch may have just settled down from another big adventure, but he is about to have a new one... It's been a month since Branch reunited with his brothers and saved Floyd, but not everything has been at peace in Pop Village. Branch has had to deal with his near insufferable brothers always bothering him, and even his new girlfriend Poppy isn't helping much. That is, until he sees a big creature fall from a tree and finds a baby dragon caught in a net with broken wings. Deeming the creature harmless due to its condition, Branch frees it from the trap and takes it back to his bunker to heal it. Unfortunately, taking care of a baby dragon is not as lackluster of a job that Branch hoped it would be. The little Chimeragon seems to go everywhere in the village and meet every troll, even though its presence would terrify everyone. Along with the Chimeragon, more dragons start to follow, and the Trolls begin to prepare to fight back. With every Troll now on high alert for dragons in their territory, Branch fears for the baby Chimeragon's safety. He's the only one who trusts the dragons, but with his new friend, maybe this could change. They could change their futures.
