Following a massive win at a competition at Maui's world-famous Jaws surf break in 2003, professional surfer Garrett McNamara comes out of retirement to pursue his lifelong dream of riding a 100-foot wave.

In 2011, the McNamaras and their team reconvene in Nazare, where they kick preparations into high gear to prepare. Garrett catches a wave that forever changes him, the small seaside town, and the legacy of the sport.

As the word gets out about Nazare, the Worlds top surfers begin to arrive for the first official competition. Concerns over safety measures, causes more worries for Garrett.
