Recently retired Air Force commando Thomas Mazuko was looking forward to a quiet future spent teaching karate in his small Tampa, Florida, studio. His dreams were of little more than days on the sandy beaches and nights in the company of his wife and children. Little did he know that his instinctive reaction to witnessing the mugging of an elderly woman would set in motion a chain of events that would drastically alter the course of his life. By sheer accident, Mazuko becomes a primary target for the wrath of a powerfully connected local syndicate figure. When the wealthy and egomaniacal Martin DeValdez sends out wise guys to "teach this upstart a lesson" Mazuko's foster son and a young student are caught up the maelstrom of uncontrolled chaos. As the level of violence escalates, Mazuko realizes that he has become the target of vengeance of a man who will stop at nothing to right what he perceives as personal wrongs. With the body count rising and the lives of his ten-year-old daughter and two-year-old son, as well as the lives of friends, new and old, hanging in the balance, Mazuko must set aside his plans for a quiet retirement and return to the skills of his past in order to fight for his life and the lives of his children.
