Seventeen-year-old volleyball star Kaylee Jordan lives a life of player rankings, constant training, and a carefully curated social media full of followers watching to see if she'll go pro out of high school like her famous mom. Her one refuge, and the thing she looks forward to every summer? The vacation her family spends in Malibu with the Freeman-Yus. This year, there’s only one problem: Kaylee and their son, Dean, dated for the past three months, and Kaylee just unceremoniously dumped him.

Hoping to spare them the worst summer ever, Kaylee comes to Dean with her unconventional solution: she’s going to walk him through her rules for getting over an ex. When Dean grudgingly cooperates, Kaylee’s got her work cut out for her. But helping Dean follow her own rules starts becoming difficult when the pressures of Kaylee’s family legacy and perfect life start to feel less like a plan and more like a prison… and amid warm California nights and stolen laughs, Kaylee feels herself falling for Dean for the same reasons and some new ones.
