German silent film starring Pola Negri.

A disfigured killer with glazed-over white eyes is doing the dirty work so that an insurance agent-doctor can get the victims' insurance money.

A 20th century European village is haunted by the ghost of a murderous little girl.

Wolf Brandin is in his mid-twenties and lives with his wife and child in East Berlin at the end of the 1950s. In West Berlin, the student of electrical engineering is recruited by the American secret service CIA. But Brandin immediately notifies the State Security of the German Democratic Republic and from then on lives a dangerous life as a double agent. When Brandin reaches the breaking point, his marriage starts to unravel because Brandin is not allowed to tell his family about his double life.

The German police cannot solve the mystery of the seven murders which have alarmed the local villagers. They call in Inspector Doren of Interpol, and the only clue the Chief Constable can give the detective is the fact that, each time a murder was committed, the electric lights in the whole neighborhood went out. The locals believe that the killings of the young girls are linked to the vague shadows in the caves under the local castle and to the mysterious Curse of the Green Eyes.
