Blockbuster Director, Renny Harlin (DIE HARD 2, CLIFFHANGER) brings one of the greatest unsolved mysteries of the 20th century to the big screen -- the controversial Dyatlov Pass Incident. In February of 1959, nine Russian hikers ventured into a remote area of the Ural Mountains in Russia. Two weeks later, all nine were found dead. Now, five ambitious American college students are issued a grant to return to the site of the original events in the belief that they can uncover and document the truth of what happened at Dyatlov’s Pass. But what they find is more shocking than anything they could have imagined. Their trek through the Ural Mountains, retracing the steps of that ill-fated journey, is plagued by strange and increasingly terrifying phenomena, all of which suggest that in spite of their desolate surroundings, they are not alone. The forces behind the Dyatlov Pass Incident have been waiting for them.
