Finland, 1942. A squad of Soviet soldiers, subjected to the mercy of the frozen Finlandic tundra that reduced their numbers night by night. The soldiers had received advice from the local people to not approach to the Ivalo mountain under any circumstance due to the rumors of something monstrous living in there. Since the Soviet captain saw it as an enemy attempt to scare them, they received orders to go and take refugee on the Ivalo mountain, to just be found slaughtered, torn apart and some even skinned, one morning by the Finlandic troops. Now, 75 years after, people still don't approach the mountain, so Andrea Everett and Dexter Hall, two expert demon hunters, have been sent there, to the Ivalo mountain, to kill whatever resides in there, to kill it once and for all... Or die trying.
