The story of "Kursk", a Russian state-of-the-art nuclear submarine that sank on August 12, 2000, about 100 miles from the Murmansk naval base, is well known. The entire crew and visiting officers of the Northern Fleet Staff were killed then. What did the sailors, trapped in its steel body feel and think about? We'll never know.

In the Canadian submarine disaster some of the sailors survived, and the Polish rescuers who fought for their lives will tell us the story of the rescue operation which will continue on Canadian soil.

There, love and feelings intertwine with the great enigma of a mysterious underwater rock cliff.

The story of this rescue mission is based in part on true facts.
