Bob Crane has long maintained a psychic connection to his twin sister, Jessica, who works as a fashion model in Milan. When Bob senses that his sister might be injured or killed, he travels to Italy to look for her, only to discover that she's vanished without a trace. Enlisting the help of about-to-retire Commissioner Danesi, Bob soon finds himself embroiled in a web of mystery and terror, when a scissors wielding killer begins to strike and all clues lead back to Jessica...
