A common man that is tired of being treated as stupid, and starts treating other people the same way, acting as a Brazilian "Manosanta" (folk healer that cures people illnesses).
Abel Amoroso, a cadet in a notary's house and responsible for taking the deposits to the bank, is kidnapped by a gang whose leader, Luis Santanelli, has an incredible physical resemblance to the cadet. The captor adopts the identity of his sosias, elopes with the loot, convinces investigators of his innocence, and marries Abel's girlfriend.
When they are killed by the leaders of the two gangs fighting for control of the underground game, the conductor who is the heir of one of them turns his musicians into gangsters.
Alberto, an employee of a car dealership, is commissioned by his boss to deliver a car that has been sold to a customer. Being a luxury car, he has no better idea than to invent an excuse to the new owner of the vehicle, delay delivery for the next day and use it to go out to have fun at night with his faithful friend Jorge. They both go to a revue theatre and, while witnessing the performance, the first vedette (Corina) faints. Then Alberto and Jorge pose as doctors, in order to meet Corina. As is to be expected, both decide to continue the deception with the passing of the days, causing the confusion to become bigger and bigger and harder to keep secret.
