Smart people try to avoid this place, because devilish things happen there: either a UFO will fly by, or the trees will catch fire on their own, or you will disappear altogether, holy, holy, holy! Well, there was one brave soul, a specialist in paranormal phenomena, Professor Khamlyasov, and he led a group of scientists there. And the expedition sank as if it had disappeared into the ground. There is no time for scientific research, and four rescuers and a dog go to the Black Swamp. These guys don't care about the mysteries of nature and the tricks of otherworldly forces. They go to the anomalous zone with one goal - to save people, and no devilry will become an obstacle for them. But reality turns out to be worse than the chilling legends. It would be better if the expedition were kidnapped by aliens - it would be easier to rescue her...
