"The Wrecking Season" (2004) was his final work, and his first documentary. He wrote, presented, and narrated the film, which his widow Jane Darke filmed and directed. "The Wrecking Season" charts the lives of Cornish 'wreckers', traditionally Cornish farm-hands who collected bulk wood that washed in after a storm, to sell for additional money and supplement their income when farming was slack, or to use to build with. More broadly the film explores the journey of long haul drift and general sea debris, notably sea beans from the Amazon basin, and tuna and lobster fisherman's tags from the Maine and Massachusetts fisheries, and how 'wreck' follows a consistent route around the Gulf Stream, arriving specifically on the west coast of Ireland and the North Cornwall coast. Nick talks to oceanographers, wood specialists, and fisherman on both sides of the Atlantic.
