Based on the best-selling autobiography "Find Away" by Diana Ned, who was regarded as the world's most outstanding long-distance swimmer in the 1970s and broke several world records. In 2013, with the help of her best friend and 35 enthusiastic supporters, the 64-year-old Ned completed her lifelong dream without a shark cage, which she had failed many times in her youth: crossing the 110-mile ocean from Cuba to Florida, becoming the first person to achieve this achievement. This dangerous sea area has the world's leading sharks, extremely poisonous jellyfish, unpredictable ocean currents, and eddies. Swimmers have tried since the 1950s, and Ned almost lost his life. After five challenges, he finally succeeded.
