San Demetrio London

The tanker San Demetrio is part of a sea convoy in the North Atlantic when it's attacked by a German battleship and heavily damaged. The crew abandons ship in two lifeboats. One lifeboat is rescued, but the other, bearing 2nd Officer Hawkins (Ralph Michael), Chief Engineer Pollard (Walter Fitzgerald) and others, drifts hopelessly. The sailors spot a burning vessel and are surprised to discover their own ship miraculously afloat. They mount an audacious plan to re-board her and return to action.
