The night on bald mountain (1998)

Everyone knows what Bald Mountain is. It's a place where all the wicked gather and have a real coven. They go there when night falls. That's where all the wolves, werewolves, witches and even real devils come together. There they brew a terrible potion. Rumor has it that if you go to this mountain once, you can see a lot of terrible things, after which you can hardly sleep at night. When their brew is fully cooked, they begin to summon all the sinister spirits to help them keep the balance in the world and frighten all the earth's inhabitants.
