xXx: State of the Union
In Virginia, a rancher discovers dead bodies on his farm and is then killed by one of the assailants. The attackers use special explosives to break into an NSA bunker beneath the horse farm. Agent Augustus Gibbons fends off the attackers before barely escaping. Shavers, Gibbons' assistant, informs him that with the attack on the NSA bunker, "Bama" Cobb also had Xander Cage apparently killed in Bora Bora. To find a new substitute, Gibbons meets with Lieutenant Darius Stone, a former U.S Navy SEAL officer, who is currently serving 9 of his 20 years sentence in Leavenworth for disobeying orders and breaking the jaw of General Deckert, who is now the Secretary of Defense.
Gibbons helps Stone break out. Stone meets with Zeke, his old partner in crime, and Lola, his former girlfriend, who now runs an exotic car shop. Stone is instructed to recover a hard drive from the NSA bunker, and he manages to escape Agent Steele at the same time. Gibbons is attacked in his house and apparently killed, with Deckert and Sergeant Cobb covering up the plot. Stone meets up with Gibbons' contact, Mayweather, to get information. Stone goes to her safe house but is framed for the murder of 4-Star General Jack Pettibone; Mayweather is revealed to be involved.
The police arrive, and Steele enters and talks to Stone, who escapes afterwards. Shavers hacks into the Pentagon to retrieve Deckert's plans. Stone infiltrates Deckert's troops aboard the USS Independence and discovers Gibbons is not dead, but being held prisoner. Stone's presence is alerted by Mayweather. Gibbons orders Stone to escape and leave him. After retrieving the plans, Stone gets into a tank and fights his way out of the ship. He learns that Deckert is planning a coup against President Sanford.
Stone makes contact with Steele and shows him the plans. The former leaves in frustration, to Steele's initial disbelief. During a conversation with Deckert, Steele realizes Stone was right. He finds Stone and tells him that Deckert wants to kill Sanford and his successors so he can take Sanford's place.
Stone, Steele, and Shavers enlist the aid of Zeke and his crew. Together, they rob an 18-wheeler secretly hauling guns and equipment to the Department of Homeland Security under the guise of a cheese truck. They end up hijacking a tank, and Stone helps Steele infiltrate the Capitol building. A shootout starts, and Gibbons kills Mayweather. Deckert and Cobb abduct Sanford while he is making the State of the Union Address. They escape on a bullet train. Jackson arrives with a car, and Stone uses it to infiltrate the train. He engages and kills Cobb before engaging Deckert, while Steele extracts Sanford. Stone jumps out after Gibbons destroys the train, killing Deckert.
The story is covered up, and Deckert is buried and branded as a hero. Sanford awards Steele and the unknown soldier (Stone) the Medal of Honor, and Stone goes back to his former lifestyle. In the now-rebuilt NSA Headquarters, Gibbons, Steele, and Shavers discuss what kind of person the next xXx agent should be. Gibbons says that he has the perfect candidate for the job.
