42-year-old Michael needs a change in his life, so when he hears about clinical trials for a new anti-depressant, he signs up to be a guinea pig--without telling his family. Because of dangerous side effects, the trial is subsequently abandoned, but Michael continues to take the pills. He loses all control and his repressed instincts resurface with incredible force and violence.—Anonymous
