James Bond infiltrates a North Korean military base belonging to Colonel Tan-Sun Moon, and poses as an arms dealer trading African conflict diamonds for weaponry. Bond attempts to assassinate Moon, but has his true identity revealed by Zao, Moon’s assistant, during the transaction when someone transmits Bond's top-secret MI6 personnel file to Zao. A chase results in the disfiguring of Zao’s face and the apparent death of Colonel Moon after Bond runs him off a cliff. Bond is captured and imprisoned by the Colonel’s father, General Moon, and subsequently tortured.
Bond is informed by M that his 00 status has been suspended. His freedom was a result of the Americans and MI6 believing he was hemorrhaging sensitive information to North Korea during his torture and they wanted to get him back under their control before he was able let out any more information. Bond, knowing that he never revealed any information, instead surmises that someone within MI6 betrayed him, first by revealing his identity to Moon and Zao, and then by revealing the identities of deep-cover operatives who were subsequently assassinated, attributed to his "breaking" under torture
