Five women go camping in a remote mountain range. None return. Chloe, Hayley, Rachel, Lisa and Zoe each have their own reasons for needing to get away. But what starts as a camping trip takes a dark turn when they start to question if they’re really alone on the mountainside. What really awaits the girls outside the relative safety of their tent – and more importantly, do they really know who’s inside it? Based upon the real events of the Dyatlov Pass Incident, this psychological horror transfers events to the modern day, exploring a mystery that has remained unsolved for 60 years. Why was the tent cut open? Why were the bodies partially dressed in each other’s’ clothing? And what was meant by the group’s chilling final journal entry; ‘We know now that snowmen exist’.
