Shortly after an American woman is murdered moodily in Paris's Montmartre district, yet strangle before, and left mutilated in a theatrical staging, causing the French authorities to call in the FBI team, a similar, yet unrelated case occurs, the first of several in short intervals. Local commissioner Pierre Clement reluctantly cooperates, and can't resist informing the media early, so the killer changes his MO and dumps the only link, his cab. Yet the team finds the key in his sickeningly frustrated past.
