Der Nachtwandler

In his youth, Leon Nader suffered from sleep disorders. As a sleepwalker, he even became violent during his nocturnal excursions and was consequently treated psychiatrically. He truly believed he was cured—until one day, years later, Leon's wife mysteriously disappears from their shared apartment. Has his illness returned? To find out how he behaves in his sleep, Leon attaches a motion-activated camera to his forehead, and when he watches the video the next morning, he makes a discovery that shatters the limits of his imagination: His nocturnal self descends into the darkness through a door he has never seen before.
