Lee Ray Oliver, cruel murderer, the court brings the death sentence by lethal injection a shot, but it is common sleeping pills. For all official documents Oliver is dead, so it is put before a choice: to participate as a guinea in the trial of a new drug that suppresses aggression or death. Oliver chooses life and Dr. Copeland takes over him patronage. During the experiment, Oliver begins to resist, and even a few times trying to escape, but the doctor stopped him and once again forced to take an experimental drug. Soon Dr. Copeland even begins to empathize with his patient, hoping to make it once again a full-fledged member of society, and Oliver begins to feel real remorse.
