In 1960s Malibu, a perky teenager with dissociative identity disorder, Florence "Chicklet" Forrest, desperately wants to become the first female surfer at her local beach. However, her ambitions are frequently dismissed by the male-dominated surfing community, and she is often ridiculed or outright ignored. Despite these setbacks, Chicklet is resilient and befriends a group of beachgoers, including the dreamy surf guru, the Great Kanaka, and a group of surfers and sunbathers, who are all fixated on riding the perfect wave, looking good, and keeping the party going. As Chicklet persists in her quest to gain respect and catch big waves, she wrestles with her multiple personalities, including one particularly assertive alter named Ann Bowman.

As the summer heats up, so does the mystery, when a series of bizarre and violent incidents start occurring on the beach. Someone is hunting the beachgoers, leaving both the future of Chicklet’s surfing dreams and the safety of the community hanging in the balance. The eclectic group of sun worshipers and wave riders find themselves entangled in a dangerous investigation as they try to unmask the culprit. In the midst of the tension and terror, Chicklet must contend with her personal challenges and surmount the stigma surrounding her mental health to protect her friends and achieve her aspirations.
