Summer camp for teenagers. The counselors and children sit around the campfire and, as usual, tell scary stories. The last one to speak is Max. He tells that not far from the camp there was once lived an ordinary farmer who drank a lot, fought in the local bar, beat his children and wife. One day he went "off the rails", took an axe and hacked his entire family to death, after which he disappeared forever. Max adds that if you say the farmer's name "Mad Marz" out loud, he will appear from the woods. One counselor jokingly shouts Marz's name loudly, and then everyone goes to their rooms to get ready for bed.
According to the legend told, a maniac appears in the camp and starts killing teenagers one by one....
