Everyone knows about the Dyatlov Pass Incident, but what if we told you there’s another, more mysterious incident that took place in Siberia’s Khamar-Daban mountains in 1993? On a seemingly routine hike, suddenly, six experienced students began convulsing, tearing at their clothes, and even bleeding out of their eyes. What’s more mysterious is that one survivor saw it all and disappeared shortly afterwards. Were they subjected to a secret military test? Experienced something paranormal next to the world’s oldest lake? Or something even more sinister on this lonely mountain pass?
