Vonny and his friends were physically and emotionally scarred for life at the hands of a psychopath during a long, deranged weekend when they were teenagers. They never fully disclosed the details. Some things are too horrifying to share. It's now 30 years later and the psychopath is being released from prison, leaving the friends with an important decision to make. Do they carry out the act of revenge they have been planning all these years, or do they try an experimental drug that promises to replace their traumatic memories with harmless ones?
