Troopers on Bald Mountain. People and non-humans come from all over Kyiv on the eve of Walpurgis Night to Bald Mountain. A mad inquisitor is sent here to cleanse it of all evil spirits and expel demons from witches. Young witches come here to find out their fate and are soon horrified to learn what awaits them. The older witches notice other creatures on the mountain. Those, in anticipation of the arrival of distinguished guests, clear the territory, expelling all outsiders. Two chosen ones become unwitting witnesses of the Last Judgment.
