Navdihujoča biografska drama, ki je nastala na podlagi resničnih dogodkov, pripoveduje zgodbo najstnice Bethany Hamilton iz Havajev. Deklica, ki je zaljubljena v morje in valove, nekega dne med surfanjem doživi napad morskega psa in ostane brez leve roke. A vedno optimistična Bethany se zaradi tragičnega dogodka ne želi odreči svojim sanjam, saj se s pomočjo podpore svojih najbližjih kmalu zopet poda na valove.
13 year-old Bethany Hamilton is a champion surfer who was born to be in the water. But after a fun night out night surfing and what should be a fun day in the water, she is attacked by a shark and loses her arm. Rushed to the hospital, she remains calm, and maintains her faith in God. Now she has to re-learn how to do everything with only one arm - including how to surf. It will take her friends, family, and her Christian faith to get her back into the water, but if that is where she is meant to be, she will find a way to get there.
