After two films of friendship and flirting, Poppy (Anna Kendrick) and Branch (Justin Timberlake) are now officially, finally, a couple. As they grow closer, Poppy discovers that Branch has a secret past.

He was once part of her favourite boyband phenomenon, BroZone, with his four brothers. BroZone disbanded when Branch was young, as did the family, and Branch hasn’t seen his brothers since.

When Branch’s brother Floyd is kidnapped for his musical talents by a pair of nefarious pop-star villains, Velvet and Veneer, Branch and Poppy embark on an emotional journey to reunite the other brothers and rescue Floyd from a fate even worse than pop-culture obscurity.
