Summer vacation on the banks of the Danube; a family is biking along the river. While his parents reminisce about their youth and his younger brothers seek his company, sixteen-year-old Dídac prefers to be alone and quiet. He’s suffering from heartbreak. But suddenly, he begins to see a mysterious boy over and over again—in the water and on land, in the distance and up close. And each time, Dídac finds himself drawn a little deeper into the stranger’s spell.
