A smuggling operation in Tampa Bay results in the deaths of Bobby Saint, the son of mafia boss Howard Saint, and Otto Krieg, an arms dealer. However, Krieg's death was faked; he is revealed to be undercover FBI agent and Delta Force veteran Frank Castle on his final mission before retirement. Enraged about the death of his son, Saint orders his men to learn everything they can about Krieg, and acquires access by bribing corrupt federal law enforcement officers for his federal service history. He orders Castle killed at a family reunion, while Saint's wife Livia requests that Castle's family be killed as well. At the reunion, Saint's men, including Saint's best friend 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.
