Every spring, the Breton deep-sea fishermen embark on a dangerous journey to the fishing grounds off the coast of Iceland. The headstrong fisherman Yann is also part of the crew every year. But this time, everything is different: the young Gaud from Paris has fallen in love with Yann, who hesitates to marry her due to their social differences. It is only after Gaud's father dies that the path for the young couple is finally clear. However, before that, Yann must undertake the perilous journey to Iceland once more.
