Overview

Longtime friends Michal and Kuba decide to illegally explore a little-known cave in the Tatra Mountains. When they get lost in the maze of passages, losing their way back, they are on their own. After three weeks, one of them, under mysterious circumstances, manages to get to the surface. Extremely exhausted, he slowly recovers, but is unable to accurately reconstruct the events of the cave or answer questions posed during the police investigation. The man finds himself facing manslaughter charges for the death of his friend - although even these circumstances are not entirely clear.

Plagued by nightmarish visions, he inevitably comes closer to confronting the truth as his worst fears awaken each night...
