A weapons dealer wanted by Interpol is found dead after washing up on shore. Surveillance shows the victim walking with Victor Hesse, the man who killed McGarrett's father and survived from the events on "Pilot". He visited a doctor whom he later kills after having the bullets removed from his torso, and has since been off the grid for four months. To track him down, Five-0 reluctantly enlist the help of Sang Min, the human trafficker arrested from the pilot. When they arrive at the bar, Sang Min betrays them and helps Hesse escape. Chin Ho tracks them to a ship, but is knocked out and awakens the next morning with a bomb attached to his neck. Hesse demands $10 million in exchange for his life, but Governor Jameson refuses to negotiate. Chin Ho, however, knows that HPD has over $28 million from a drug bust three years previously until $200,000 ended up missing, resulting in Chin Ho's corruption charges. Five-0 break into the vault and "borrow" the money they need. When they meet however, Hesse burns it. Kono shoots him, and McGarrett coerces him to deactivate the bomb. In the end, as Five-0 celebrate Christmas, Hesse is seen meeting with Wo Fat (Mark Dacascos) in prison, who wants to know how much McGarrett knows about his father's case.
