Exploitation horror from Italian director Lucio Fulci in which a series of murders in a small Sicilian town bring its inhabitants under suspicion. With the police baffled by the strangulation of a preadolescent boy, newspaper reporter Andrea Martelli (Tomas Milian) begins an amateur investigation into the murder. A number of suspects present themselves: Patrizia (Barbara Bouchet), a socialite hiding out in the town until a drugs scandal blows over; Maciara (Florinada Bolkan), a beautiful young woman who dabbles in black magic; and Giuseppe (Vito Passeri), the town outsider. As the body count begins to rise, can Andrea get to the bottom of the scandal before yet more lives are lost?
