Seeking recognition and money to save his ailing business, English amateur sailor Donald Crowhurst (Colin Firth) decides to enter the Golden Globe Race, a nonstop solo sailing race around the world. In October 1968, he leaves Teignmouth harbor in Devon in a home-built boat, leaving his wife (Rachel Weisz) and children on the dock. He soon realizes that he has completely underestimated the adventure. His boat is not seaworthy and he has far too little experience. In a desperate attempt to avoid loss of face and bankruptcy, he makes a decision with profound consequences. Oscar winner James Marsh (The Theory of Everything) turned this unlikely true story into a loving portrait of a man guided by his dreams.
