Short Night of Glass Dolls (1971)

Greg Moore, an American journalist, who is visiting Prague with his girlfriend, is found dead. However, he's actually only temporarily paralyzed, but the coroner fails to realize this, and proceeds to prepare him for autopsy. While Moore awaits his doom, he tries to recollect what has happened to him. It all starts when his girlfriend disappears. He asks his friend, a local journalist, for help. They discover that this was just the latest in a series of disappearances of young pretty girls in the area. Their investigation leads them to a strange high profile private club, whose affluent members practice odd ritualistic orgies and bizarre dark rites.
