A gang of robbers steals thousands of euros in a provincial bar without imagining that the owner of the business is Cagliostro (Tony Sperandeo), a shady individual linked to the criminal underworld. He tracks down the gang of robbers, offering them the opportunity to collaborate with him, by sneaking into the mansion of the elderly Chinese businessman Hung (Hal Yamanouchi), where they will have to steal a green jade pendant for him. In exchange for the success they will be able to keep all the money stolen from the bar, but they will discover that the medallion is around the neck of Hung's daughter, Sofia (Martina Angelucci), in a coma and kept alive through a mysterious ritual. And it is only the beginning of a long night of blood and violence.
