Italian horror. With a serial killer on the loose and murders taking place frequently across town, Inspector Bruno Moretti (Luis Emilio Rodriguez) surmises this new killing spree is linked to the disappearance of a young girl 15 years prior. The missing girl's father, Vittorio Visconti (Raul Gederlini), realises the new killings all appear to be linked to Dante's 'Divine Comedy' but will this be able to help Moretti solve the case and find the killer?
