A smuggling operation in Tampa Bay results in the deaths of Bobby Saint, the son of boss (crime) Howard Saint, and Otto Krieg, the arms dealer. Krieg is revealed to be undercover Federal Bureau of Investigation agent and Delta Force veteran Frank Castle on his final mission before retirement. Enraged over the death of his son, Howard Saint acquires confidential information regarding Krieg and learns of his true identity. He orders Castle killed at a family reunion, while his wife Livia requests that his family be killed as well. At the reunion, Saint's men, among them Quentin Glass and Bobby's identical twin, John, kill Castle's entire family and shoot Castle, leaving him for dead. Castle survives and is nursed back to health by a local fisherman.
