Buenos Aires, 1962. The life of Jorge Rizzi, a shy corporate employee, takes a turn when he participates in a hypnosis session that frees him from his inhibitions and reveals his wild and seductive alter ego: Dr. Tangalanga. At first, he uses his new powers to cheer up Sixto, a convalescent friend, and win over Clara, the receptionist at the sanatorium where he is hospitalized, over the phone. But things don't take long to get out of control.
