By age 13, Bethany Hamilton had already collected a shelf of awards for her surfing skills. Then, while on her board off the coast of Hawaii, she lost her left arm to a shark attack. Her remarkable recovery — she was back in the ocean in major surfing competitions the following year — made her a media sensation and the subject of the 2011 movie Soul Surfer. Now, in director Aaron Lieber’s inspiring documentary, filmed over four years, Bethany’s magnificently improbable triumphs and challenges continue as she meets and falls in love with her husband (their wedding takes place underwater!), becomes a mother, and prepares to take on the mammoth wave known as “Jaws” off the coast of Fiji. Featuring archival footage of her Hawaii childhood, magnificent surfing scenes shot by Lieber, and candid interviews with her family, friends, and Bethany herself, Bethany Hamilton: Unstoppable tells a story so improbable it could only be true.
