Darryl Irving, a sober, thoughtful African American teacher, gets charged with assault and forced to go through the surgery "Lobotomy" under the pretext of improving his behavior because of the fight he had with a drunk, Seth, on the street one night. After the surgery, his girlfriend, Lydia Keats, attempts to reconnect with "improved" Darryl, as she is feeling guilty about the night she took him out for the date, only to find out that Darryl now has changed and become nothing more than an empty man who cannot react humanly to anything. Simultaneously, Darryl starts seeing his alter ego, the avatar of the anger against racism that he had through his life, in a mirror, which encourages Darryl to revenge on white people...
