Narrated by Tilda Swinton, Deep Water is the stunning true story of the fateful voyage of Donald Crowhurst is a 36-year-old father of four whose marine electronics business is ailing. Staking everything in his attempt to win the fastest voyage prize, he leaves behind his wife and young children to enter the most daring nautical challenge ever - the very first solo, non-stop, round-the-world boat race.

As the race progresses, Crowhurst's reports of his positions at sea show that, after a slow start, he is beginning to cover ever-greater daily distances, surprising press and public alike, before he begins to set new world records for distances covered in the course of a day. Headline after headline is being printed - not just across Britain but also across the globe. Crowhurst is fast becoming the darling of the tabloids, hailed as a nautical wonder with the world's gaze upon his lonely and potentially life-threatening journey.

But, as the world waits on tenterhooks for this extraordinary man to cross the finish line and sail into port to a hero's welcome, the jaw-dropping truth of his ten month voyage is revealed that things have gone terribly wrong for Donald Crowhurst...

From the producer of Touching the Void, Deep Water is directed by Louise Osmond and Jerry Rothwell. Deep Water uses Donald Crowhurst's original 16mm films and tape recordings to re-construct his extraordinary journey. Much of this incredible archive has not been seen for over 30 years and was only recently re-discovered by the production. Deep Water also includes interviews with Sir Robin Knox-Johnston, Francoise Moitessier and marks the first time in thirty years that Donald Crowhurst's family have broken their silence to talk about the events.
