At first glance, Ken Boyd may seem like an average comic enthusiast, living with his mother and working to make ends meet as an underpaid, underappreciated ice cream parlor attendant. But Ken has a dirty little secret: he fantasizes about killing people. After being released from a stay in the loony bin for severe mental trauma suffered when he was beaten and tortured by a gang of high school thugs, Ken's repressed anger suddenly reaches a boiling point. He begins to hunt down his tormentors, one by one, and exacts his bloody revenge - all the while forming an unconventional bond with his estranged 11-year old daughter.
