In early 1945, the Nazi submarine U-745 is lost and the body of its captain is found frozen on the island of Foglo. For nearly 70 years the U-boat's fate has remained a mystery. Now, after over a decade of painstaking research and underwater exploration, the mystery of the U-745 has been solved by the members of Badewanne, a Finnish diving team. While searching, they dispel the myth of the Louhi, a Finnish minelayer that some thought was sunk by its own mine and discover a type of submarine some say was never built. This group of highly skilled technical divers journeys deep below the frigid waters of the Baltic to reveal the secrets of the Nazi sunken sub.
