Bond investigates into the sinking of a British warship in Chinese waters, the theft of one of the ship's cruise missiles—and the shooting down of a Chinese fighter plane. He uncovers a link to media mogul Elliot Carver which suggests that Carver had purchased a GPS encoder on the black market, finding it in his headquarters in Hamburg.
Bond encounters Chinese agent Wai Lin in Vietnam, who is also investigating the matter and the two agree to work together. They discover that Carver had used the GPS encoder to push the British ship off course and into Chinese waters in order to incite a war for ratings. With the British fleet on their way to China, Bond and Wai Lin find Carver's stealth ship, board it and prevent the firing of a British cruise missile at Beijing. They blow a hole in the ship, exposing it to radar, leading to its sinking averting war between Britain and China.
