On the evening of December 24, 1986, the Icelandic freighter Sudurland sent out a distress signal. It had set out to deliver a load of pickled herring to Murmansk, Russia and run into trouble in the harsh North Atlantic. Only five of the eleven crew members survived the shipwreck. When a Danish rescue helicopter reached the scene, the men had been floating in the icy sea on a leaky life raft for hours. But what caused the wreck? Official investigations spoke of loading errors and inadequate safety precautions, but the British press speculated that the ship might have collided with a Soviet submarine. Journalist Óttar Sveinsson looked into the open questions about the event. Based on his research and new interviews with the survivors, the film gives an account of the dramatic shipwreck.

The film will be screened at the Seven-Seas-Chapel of Germany's National Memorial of Seafare at church St. Jakobi.
