Djúpið

Based on the true story of Guðlaugur Friðþórsson, a fisherman who survived six hours in freezing waters after his boat capsized off the south coast of Iceland in 1984. Guðlaugur (Ólafur Darri Ólafsson) sheds his heavy clothes and swims for six hours, talking to seagulls, before reaching safety. He becomes a national hero, but the scientist examining him finds special enzymes that allow him to regulate body temperature seven times longer than average - a phenomenon that remains unexplained.
