Bethany Hamilton: Unstoppable chronicles the life of Bethany Hamilton, a professional surfer who tragically lost her left arm after a tiger shark attacked her while she was surfing along Tunnels Beach in Kauai, Hawaii, in 2003. Through interviews with Bethany and her family, personal videos, and archival material, the biopic shows how Hamilton recovered from the attack, went back to the seas to surf and compete again, and formed her own family.
