Kurt, an apprentice in a fish combine, is an ambitious loner. He wants to show what a good sailor he is at a regatta, but fails because of his recklessness and the storm. Disappointed, he seeks affection from the girl Anke, but she loves the apprentice Hannes. During a trip together with Captain Laue, who presents himself as a fatherly friend to Kurt, the boys get into an argument. However, when Laue makes an unscheduled call at Bornholm and Kurt discovers that Laue wants to sell the cutter's catch and equipment and flee, he buries his differences with Hannes. Together and with the help of the old fisherman Jens, the boys rescue the cutter.
