During a debate of journalists with the renowned psychiatrist Dr. Sérgio and José Mojica Marins a.k.a. Zé do Caixão, Sr. Sérgio presents several cases of kinky sex and orgy associated to the use of drugs. The journalists defend that the cases are related to perverts and criminals, but Dr. Sérgio blames the influence of drugs for the violence. Then Dr. Sérgio invites four persons from different classes to use LSD and analyze the effect of Zé do Caixão's films in their twisted minds to prove his theory.
