A tantalising passage in a 19th-century treasure hunter’s journal inspires a family of modern-day adventurers to find and surf a spectacular wave in some of the most remote and dangerous waters of the Atlantic Ocean.

For renowned skipper and thrill-seeker Matt Knight, the challenge of sailing to such an unpredictable and uncharted region is impossible to resist. Joined by world-class big wave surfer Andrew Cotton, plus family and friends, the group faces serious injury and life-threatening challenges as they fulfil their quest.

Narrated by Charles Dance, Mikey Corker’s exhilarating documentary is an intimate and epic portrayal of extraordinary individuals who push the very limits of exploration. It is filmed in some of the most beautiful islands and dangerous waters in the Atlantic, from the West Coast of Ireland to the mighty waters of Nazaré.
