The Deep is based on an astonishing true incident on a cold night in March 1984, a few miles off the South Coast of Iceland, when a fishing boat sank with its men. One of the crew members miraculously managed to survive, by swimming to shore. After five hours in the ocean, the exhausted young hulk washed ashore, only to find himself on a deadly, uninhabited lava field. The film depicts his journey and how he survived through the aftermath.
