Open-water swimmer, Kim Chambers, chases her biggest dream yet: to become the first woman to complete a solo swim from the Farallon Islands to the Golden Gate Bridge - a 30-mile stretch of water known for frigid temperatures, swirling currents and the world's largest Great White sharks. Many consider it to be the hardest marathon swim in the world, and rightfully so, as only four men have completed the swim. Through the physically and emotionally challenging lead-up to the swim, the swim itself, and the candid interviews with her and others, the film presents a look into what propels Kim to conquer her fears, pursue her passions and achieve her greatest potential, all while inspiring others to do the same.
