Synopsis: Karim and Lena know better than to cross the moors, even though it is a shortcut, because it is commonly known that those moors are haunted by witches. Somewhere deep inside the Haunted Moors a dark secret is hidden. But Karim and Lena want to know what happened to their classmate Rennie, who disappeared so suddenly last summer. What is the truth about the white witch and what happened at the old water mill in ancient times?
