Nov 1985
A Brazilian scientist invents the KL7, which serves to deactivate all nuclear weapons. Created for peace, it can, however, serve hidden interests when it is robbed by dangerous bandits. Pedrinho and Detective Borges then set out to investigate the case and try to find the device. In another pole of the action, an American film team appears on the site, bringing Rut Davis (Zilka Salaberry, Dona Benta herself), a very modern actress who is interested in Visconde, and Sarah Maughan (Jacira Sampaio, Aunt Nastácia herself) a crazy jazz singer.
