An Unknown Compelling Force is the true story of the Dyatlov Pass Incident, known as Russia’s greatest unsolved mystery. In 1959 a group of nine student hikers were attempting a difficult winter expedition in the remote Ural Mountains of Russia, when a mysterious event led to their horrific deaths, shocking the nation. The Soviet Government and fellow students uncovered the grizzly remains of the hikers. Found a mile from their shredded tent, the hikers seemingly flew into the freezing temperatures without their winter clothes or boots. Adding to the mystery, many of their bodies had suffered brutal and inexplicable injuries, and some even showed traces of radiation. The investigators at the time closed the case, stating that the hikers died from “An Unknown Compelling Force.” For more than 60 years the story has been shrouded in mystery and conspiracy theories, suggesting everything from UFOs and murder to a Soviet Government cover-up. This documentary features interviews with Russian investigators, a former Moscow Times journalist, and friends of the hikers. Adding a new perspective to the case, the film also interviews U.S. experts including a former FBI Agent, to finally reveal the stunning truth of The Dyatlov Pass Incident.
