Vietnam War veteran John Eastland lives in New York City, struggling to adjust to civilian life. When his best friend and fellow vet, Michael Jefferson, is brutally attacked by a street gang and left paralyzed, John is pushed to the edge. In anger and grief, he decides to take matters into his own hands. He hunts down the gang members responsible, exacting brutal vengeance. John’s actions, however, do not stop at the gang members; driven by a desire to rid the city of its criminal element, he expands his mission to tackle the widespread corruption and crime, targeting pimps, mobsters, and other criminals.

As John's notoriety as a vigilante grows, the city is thrown into chaos, drawing intense media attention and public debate. His methods and escalating violence attract the attention of Detective James Dalton, who is determined to bring him to justice. While some see John as a hero cleansing the streets, others view him as a dangerous, out-of-control vigilante. As the violence escalates, the story delves deeper into the moral ambiguity of John's quest for justice, raising questions about the price of vengeance and the consequences of taking the law into one's own hands.
