Foreign agents from an unidentified nation clandestinely install on radio and TV antennas in Rio de Janeiro devices that emit subliminal waves that alter the perception of the population. They aim to transform the people into an aggressive and imbecile mass, leading the country to chaos, allowing the government to be taken to usurp Brazil's natural wealth. A journalist, Carlos, accompanied by chemist Laura Leal, begins to investigate a series of facts and discovers those responsible for the disturbances. (DVD 2016 - Filmes Clássico - Rio De Janeiro)

Foreign country wants to perpetrate a "coup" in Brazil. They employ a new technique of subliminal messages, which are transported along with radio and TV waves. In no time, the population gets deranged and the country dives into ultimate chaos. Only a few people who don't watch television nor listen to radio are immune to it, and have the responsibility to abort the scheme, without really knowing what they're dealing with.—[email protected]
