In a little village located near the Czech-Hungarian border, a young woman named Johanna disappears one day under mysterious circumstances. At first, the trail leads to the family's dilapidated estate. A murder has been committed here. Suspicion falls on Daniel, Johanna's half- brother, and Thierry, a neighbor. Both were part of a mysterious world created, to all appearances, by Johanna, a world whose very existence was threatened through the intrusion of a stranger, Daniel's girlfriend; a world which had to be defended.
