The year is 1910. In the rural German village of Vandorf, seven murders have been committed within the past five years, each victim having been petrified into a stone figure. Rather than investigate it, the local authorities dismiss the murders for fear of a local legend having come true. When a local girl becomes the latest victim and her wiktionary:suicided#Adjective lover made the scapegoat, the father of the condemned man decides to investigate and discovers that the cause of the petrifying deaths is Magaera, the very last of the snake-haired Gorgon sisters who haunts the local castle and turns victims to stone during the full moon.
