After her mother’s death, Faun Novak, a naïve college dropout, grabs her Polaroid and hops a Greyhound to Los Angeles. There, she reconnects with her charismatic childhood friend Josie, now an up-and-coming model and muse. To make their reunion even sweeter, Josie is now dating Cal Holiday, the frontman of the superstar rock band Holiday Sun. Among the band's groupies are a doting high school girl at war with her mother; a drug-dealing wife and new mom who longs to be a star herself; and a cynical mover-and-shaker with a soft spot for Holiday Sun’s bassist. But just as everything is going great and her boring, old life is falling away, Faun realizes just how blind she has been to the darkest corners of this glamorous musical dreamland as the summer heats up and everything spirals out of control.
