In a flashback, an infant Branch and his four older brothers John Dory, Spruce, Clay and Floyd perform as a boyband called BroZone.
When their clashing egos prevent them from performing the "Perfect Family Harmony", a powerful ability that Trolls can achieve when they are in complete sync, the brothers argue in anger and went their separate ways.
They are interrupted by John Dory, who reveals that Branch's closest brother Floyd has been captured by Velvet and Veneer, two Mount Rageon teenagers who wish to be pop stars.
The siblings have trapped Floyd in a diamond perfume bottle, which they use to extract his essence and improve their singing, although the process could eventually kill him.
As the Perfect Family Harmony is the only thing that can destroy diamond, Branch reluctantly agrees to help John Dory find their brothers and rescue Floyd.
When his brothers decide they will split up again after saving Floyd, Branch scolds them for still treating him like a baby, revealing to them that he lived his whole life alone after their grandmother got eaten.
Branch, Poppy and Tiny locate Floyd on their own, but Velvet and Veneer capture John Dory, Clay, and Bruce, making a rescue even more difficult.
They, along with Poppy and Viva, perform the Perfect Family Harmony and break free of their prisons just as Floyd loses the last of his essence and dies, but he is quickly revived.
The Trolls return to Vacay Island and witness BroZone's comeback concert, joined by Kismet, another band Branch was once part of.

"[32] Tatiana Hullender of Screen Rant rated the film 2.5 out of 5 score, writing "Trolls Band Together shows clear signs of franchise fatigue, but a few new songs and vivid animation choices keep it afloat a little longer.
