Three children disappear in 1970 in a town in the Ebro delta. Their bodies will never be found, as if they had been swallowed by the salt marsh. After twenty years, and days after the disappearance of the father of one of the children, an arm appears brutally severed in the middle of the reeds. What is the relationship between these facts? The arrival of Dimitri and de la Vella, who are fleeing the war that has broken out in the Balkans, will make August Lehmann have to face a past that has always haunted him.
