Neprijatelj (2010)

In Bosnia in 1995, the civil war signed a peace agreement, and a team was tasked with clearing mines along the border between the two sides. In an abandoned factory nearby, they found a man locked up in the basement. No food, no water, no light. He looks like he's waiting for them. The soldiers took him back to the post, but could not find out his identity. He refused food and drink and looked obedient. The next day, his soldier was found missing. On their way back to the factory, the soldiers found the bodies of many soldiers and were ambushed by unidentified armed men. After paying one of them, they took the prisoners back to the camp. When he saw the man rescued from the cellar, he told the soldiers that you had released the devil. As a result, more strange legends spread between them, the team lost all contact with the base headquarters, and the originally cleared mines surrounded them overnight.
