Two days before her 40th birthday, Los Angeles rock musician/tattoo artist Jacki is considering throwing in the towel on her dreams of stardom. As front woman for the all-female band Clam Dandy, she gets the band booked into plenty of local clubs, but the big break she keeps hoping for never seems to materialise. To add to her frustration, her band resembles a dysfunctional family: drummer Sally, the band's youngest member, is the live-in lover of guitarist Faith, and bassist Tracy, is an addict whose habits are funded by her wealthy father.
