Cubby Clark's life is falling apart. All she wants is to 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, he rockets to overnight, solo stardom with a hit single about how bad she is in bed. With a fractured band, a publicly adored toxic ex, and a horrible case of writers block, her only comforts are 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 that obviously means nothing for these two totally heterosexual gal pals), Cubby and her band find themselves redirecting the spotlight as tabloids eat up the rumored love triangle between Cubby, Harry, and Connor.

Thrust by their label into a whirlwind tour, Cubby wants nothing more than 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 notoriety, 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.
