Filmen baseras på en sann händelse.

Bethany was born to surf. A natural talent who took to the waves at a young age, she was leading an idyllic, sun-drenched, surfer girl's life on the Kauai Coast, competing in national competitions with her best friend Alana, when everything changed in a heartbeat. On Halloween morning, Bethany was on a typical ocean outing when a 14-foot tiger shark came out of nowhere and seemed to shatter all her dreams.
