A swell rises in Nazare, Portugal and big wave surfers Garrett McNamara, Andrew Cotton, and Hugo Vau set out to ride it. Garrett McNamara resides in the north shore of Oahu with his wife Nicole McNamara and their children. Nazare is a small town in Central Portugal that produces some of the most impressive but deadliest waves on the planet. When Garrett and Nicole arrive at the hotel, they discover that swell has reduced to smaller waves, giving Garrett and and his team only 24 hours to prepare. They head to the warehouse to prepare gear and with safety always being at the top of the list, they take extra precautions. Garrett's water team is carefully chosen; it consists of Andrew Cotton and Hugo Vau. In 2014, Andrew Cotton rode one of the biggest waves at Nazare known to man, while Hugo Vau has always been a waterman and is skilled in a range of water-related, recreational activities from fishing to surfing. The team heads out and take turns surfing the massive waves produced by Nazare's canyons. Antonio Silva suffers a shattered knee cap after a wiped out and barely makes it to shore alive. Rodrigo Koxa and Rafael Tapia are in trouble as their jet ski is taken out by a huge wave and both are at the mercy of the North Shore as they are pushed towards the rocks. With the help of Nicole, Garrett is able to successfully rescue his fellow big wave surfers from harm.
