After the neighbor's body is discovered, Carol soon becomes the prime suspect in the investigation but more is going on than meets the eye. Carol’s father is receiving blackmail phone calls, her husband is conducting an affair and her daughter is leading a dangerous investigation of her own. Meanwhile, two ghoulish hippies that appeared in Carol’s dream show up in real life.
As will almost all Fulci films, the pacing isn’t particularly good. Scenes of pure inspiration, such as the ten minutes sequence where a motorcycle-helmed killer chases Carol from the catacombs of an old church to the rooftop, are wedged between scenes of clunky police conversations. Then too, the acting is universally wooden with no memorable performances (either good or bad).
