The Cave Man is an exceptionally moving portrait of a brutalized man named Ja Feng, who has survived punishment in a 3 x 4 foot solitary cell for a miraculous nine months, a time that has forced him to question his basic human faculties. The Cave Man follows Feng as he is released from his solitary confinement and as he integrates with fellow prisoners who view his skeletal figure and screaming fits as freakish. It follows him through his heartbreaking attempts to assimilate, to reestablish familial bonds, and to seek an ordinary human experience.
