In Rome a maniac kills several prostitutes torturing them with a razor. Soon they are informed that the murderer kills the victims not only with a razor, but delivers the deathblow to them with a bolt gun. Stella, a luxury call girl, learns about the murder of Bruna, a fellow streetwalker and old friend. Only Bruna's colleagues attend the funeral. Nadine, an experienced sex worker with a cheerful but tenacious personality, decides to organize a group of her fellow prostitutes in order to protect themselves and to discover the identity of the serial killer before he strikes again.
