A deranged killer is injecting beautiful women with the poison of a rare wasp, paralyzing them and forcing them to witness their own brutal murders. Academy Award nominee Giancarlo Giannini (SEVEN BEAUTIES, HANNIBAL) stars as the dogged detective who takes the case only to find himself trapped in a web of immorality and murder. From the tantalizingly erotic opening to its vicious stunner of an ending, experience what is considered to be one of the most riveting and acclaimed films in the entire giallo genre. Claudine Auger (THUNDERBALL, TWITCH OF THE DEATH NERVE), Barbara Bouchet (CASINO ROYALE, DON'T TORTURE A DUCKLING) and Barbara Bach (THE SPY WHO LOVED ME, SHORT NIGHT OF THE GLASS DOLLS) co-star in this rarely-seen classic directed by Paolo Cavara (MONDO CANE) and featuring one of Ennio Morricone's best scores ever, now transferred from the original camera negative and available for the first time ever in America.
