剧情简介：An unseen killer is murdering people that know too much in connection with an earlier unsolved case of a missing girl. I like the giallo genre, but this one by Tonino Valerii is laid back to the point of being tedious, a few gory set-pieces can't even help this film. The ending is horribly cliché and the film has one scene that featured a fully naked prepubescent girl that repulsed me. There is NO reason to put a nude eleven or twelve year-old in any film. EVER!
