The Cursed Dagger(1965)

A completely naked man rides a motorcycle through the city. He arrives on a bumpy path at the edge of a wood. There he sees a scarecrow. He grabs his clothes to dress himself in them and hears a voice. He turns around and sees a hanged man with a dagger in his heart. A message hangs from the hanged man warning: “Whoever you are, if you remove the dagger from my heart, you will be cursed. » Fascinated, he goes beyond the prohibition. Struck by the curse, he transforms into a nightmarish creature, ready to relive the ordeal of his predecessor by liquidating everyone.
