An international crime gang is very interested in stealing this equipement to sell it to the higher bidder of lawless nations. Menaced, the scientist, who was friends with Nick Carter's father, calls Nick for help. At Nice airport, Nick Carter escapes death, but that night he is unable to stop Formenter's murder. He suspects Bruno, Formenter's adoptive son, and Tonio, the owner of a bar near Formentier's home. Bruno is actually after Formenter's heritage, and for that he tries to kill Catherine, Formentier's granddaughter. Therefore, Nick Carter finds himself against more than a gang, but he will uncover the plots, in time to break every gangster apart.
