Originally Operazione Paura, this Mario Bava horrorama has travelled under a multitude of English-language titles: Operation Fear, Kill, Baby Kill, Curse of the Dead and Curse of the Living Dead. The scene is a remote village, where a brutal murder has occured. Things get curiouser and curiouser when investigating detective Piero Luilli likewise falls victim to the killer. The culprit is the revenge-driven ghost of a young girl. All you-know-what breaks loose during the finale, which pits the spectral murderer against coroner Giacomo Rossi-Stuart, nurse Erika Blanc, and village sorceress Labrienne Dali.
