Bethany Hamilton: Unstoppable

Born into a family of surfers in Kauai, Bethany Hamilton began surfing competitively at eight years old. In 2003, at age 13, she was out surfing when she was attacked by a 15-foot tiger shark, a run-in that cost her her left arm. But not only did she survive the attack—she was back on the competitive circuit just a year later. More than a decade later, Hamilton undertakes the greatest challenges of her life.
