Two Finnish filmmakers and a team of international divers go in search of a WWII German U-boat and attempt to uncover the facts of a 60-year mystery.

Soviet sources claimed that their submarine, the Lembit sunk the boat, but the official story has never been considered a satisfactory explanation so the filmmakers decide to do some digging of their own.
