The novella tells the story of Hauke Haien, related to the narrator by a schoolmaster in a small town in Northern Frisia. Hauke is the son of a farmer and licensed surveyor and does his best to learn his father's trade. He even learns Dutch so he can read a Dutch print of Euclid's work on mathematics and geometry. Over time he becomes very familiar with the dykes along the local coast and begins to wonder if it would not be better to make them flatter on the sea side so as to reduce their windage during floods.

When local Deichgraf Tede Volkerts fires one of his hands, Hauke applies for the job and is accepted. He soon becomes a great help for Volkerts, which makes Ole Peters, the senior hand, dislike him. Tensions rise even more when Hauke begins to show interest in the Deichgraf's daughter, Elke. Hauke even proposes marriage, but she wants to wait.

After the unexpected deaths of both Hauke's and Elke's fathers, the people of the village must choose a new Deichgraf. Hauke is actually already doing the work, but does not hold the necessary lands required for the position. However, Elke announces that they are engaged, and that he will soon hold her family's lands as well. With the traditionalists satisfied, Hauke becomes the new Deichgraf. However, the people soon start talking about his white horse, which they believe is a resurrected skeleton that used to be visible on a small island, but is now gone.

Meanwhile Hauke begins to implement the changes to the form of the dykes that he has envisaged since childhood. However, during a storm surge several years later, the older dykes break and Hauke has to witness Elke and their daughter, Wienke, being swept away by the water. In agony, he drives his white horse into the sea, yelling, "Lord, take me, spare the others!"

The novella ends with the schoolmaster recounting that after the flood the mysterious horse skeleton was once again seen lying on the small island off the coast. Hauke Haien's dyke still stands and has saved many lives in the hundred years since its creator's tragic demise. And the older ones in the village say that, on stormy nights, a ghostly rider on a white horse can sometimes be seen patrolling the dyke.

Thomas Mann called it a "tremendous tale, with which Storm took his conception of the novella, as epic sister of drama, to unprecedented heights".[1] Michael Dirda says that it is arguably the greatest 19th century German novella.[2]
