In late 1980s Los Angeles, Jacki and her all-girl punk rock band, Clam Dandy, are trying to make it big. On the verge of turning 40, Jacki decides that if the band's one last shot at the big time is unsuccessful, she will give up her dreams of stardom.

The Suburbans, a one-hit-wonder new wave band from the '80s, reunite at their bassist's wedding, where a promising young record executive sees the ensemble perform. When she encourages them to launch a revival, the group must weigh their dreams of fame and fortune against the reality of their relatively quiet domestic lives.
