Six drama students, on the verge of graduation, venture into the Swiss Alps for an excursion designed to confront their fears through a series of challenges. Their plan includes an overnight stay in a remote underground bunker. Initially joking about the resemblance to *The Blair Witch Project*, the experience quickly becomes a genuine test of courage. This low-budget horror film from director Stefan Jäger takes viewers into the unsettling depths of the Swiss Réduit, a massive World War I-era defense complex.
