Based on a true story from the fateful day of August 29, 1943, when the Germans disarmed the Danish army and navy. The minesweeper MS 1 plays the leading role in the film about the ship that refused to surrender. The commander, Captain U.H. Gad, camouflaged the boat as a tugboat under the name 'Sorte Shara'. With Sweden as its destination, the boat set sail and experienced hours of excitement as it approached the German observation posts.
