Undercover cop tracks down a Milanese criminal outfit. DVD Year 1975 Studio Music Video Distributors Genre Suspense MPAA Rating Not Rated Color Color Runtime 92 Animated Live-Action Full Synopsis In the wake of the success of Dario Argento's ground-breaking giallo The Bird with the Crystal Plumage, numerous other directors stepped forward to try their hand at these lurid murder-mysteries. At the forefront was Sergio Martino The Strange Vice of Mrs. Wardh, Torso , whose sensual 70s thrillers starring Edwige Fenech and George Hilton are widely celebrated as some of the best the genre has to offer. The final of Martino's six gialli, The Suspicious Death of a Minor combines conventional giallo trappings with elements of the then flourishing poliziotteschi crime thrillers. Claudio Cassinelli What Have They Done to Your Daughters? stars as undercover cop Paolo Germi, on the trail of a Milanese criminal outfit following the brutal murder of an underage prostitute. But a killer-for-hire is also on the prowl, bumping off witnesses before they have a chance to talk...
