Cubby Clark's life is falling apart. All she's ever cared about is make music, but on the brink of hitting it big, Cubby's on-again-off-again boyfriend and lead of her band, Connor, abandons the group. What's worse, his solo career rockets to overnight stardom based on a hit single about how bad she was in bed. With a fractured band, a toxic ex airing her dirty laundry in every interview, and a horrible case of writer's block, the only thing she can take comfort in is her best friends and fellow bandmates, Darcy and Harry. But, when an inadvertently romantic picture of Cubby and Harry goes viral the same night Cubby and Darcy hook-up (something obviously very normal for these two totally heterosexual gal pals) Cubby and her band find themselves in the spotlight as tabloids eat up the rumored love triangle between Cubby, Harry, and Connor. Thrust by their label into a whirlwind tour, all Cubby wants is to turn to Darcy for support. But ever since the passionate hook-up they never talk about, there's nothing but tension and distance between the usually inseparable pair. Under the pressure of newfound fame, an extremely dirty tour bus, and long buried feelings, Cubby and Darcy have a single summer to unravel the truth of what they mean to one another, or face losing the other forever.
