Elena, Miriam and Anna, the foxes of the night, are three beautiful women but they are also three special agents of the police headquarters in Rome. One evening they are given the task of participating in a high fashion show: a tip-off has arrived on a drug game that should be exchanged there. At the fashion show everything happens regularly, except for the attempt to snatch a beauty case from one of the models. The next morning, however, Daniela, the wearer affected by the snatch, is found dead and it turns out that the snatcher was the guardian of Eng. Mauro De Mauro, rich builder. Foxes begin to investigate.
