The story begins in North Korea when Evelyn Sauter (by) , an American businesswoman, is arrested by the Korean People’s Army for espionage. The sturdy soldier abused the American woman time and time again, forcing her to admit that she was an American agent. Fortunately, after a German biologist who admired her, the United States finally agreed to exchange hostages for Schott. After Sauter escaped from the sea of suffering, he was moved by the man who was running around to rescue him, so the two finally came together.
After another period of time, Sauter enjoyed the meticulous care of her husband every day, and the two lived happily together. Until one day, the CIA caught a Russian agent, and Sauter, as a CIA operative, interrogated him with her boss. However, the results of the interrogation made everyone stunned. The Russian agent admitted that he led a secret spy organization in the former Soviet Union. The members were all underage children. He brainwashed these children before sending them to the United States to play their role in the future. The old agent also revealed that one of his trained agents will launch an assassination of the Russian president visiting the United States in the near future, and the name of this agent is-SALT, Sauter, Evelyn Sauter. He hurriedly sent off the old Russian spy, Schott faced the suspicious eyes of his colleagues, and hysterically asked whether her husband was safe, because she thought the other party must have kidnapped him to intimidate herself. Sure enough, she tried to call home and her husband should be at home but no one answered the phone.
Soon new bad news came, and the old Russian spies took advantage of the unprepared CIA guards to kill him and successfully escaped from the CIA headquarters. But Schott’s boss, who rushed to command, found that Schott, who was suspicious, was also fleeing the headquarters building. Sauter's colleagues thought that this was a manifestation of her guilty conscience, so they even believed that she was indeed a Russian agent. After a fierce pursuit, Sauter escaped from the police and the CIA.
The Vice President of the United States passed away during his term of office. Dignitaries from all over the world came to mourn, and the Russian President was among them. The ceremony will be held in the cathedral, and Sauter, dyed in black hair, also enters the church. She created an explosion that caused the Russian president to fall into her trap alone, and eventually shot and killed the Russian president in front of a black CIA colleague who had always believed that she was a Russian agent. Seeing that the Russian president gradually stopped struggling, Schott dropped his pistol and surrendered to the black agent.
However, on the way to escort Sauter, she once again successfully caused a police car accident and escaped again. Schott, who had escaped, came to a dilapidated ship by the sea, where the old Soviet agent who had successfully escaped was also waiting for her. It turns out that Sauter is really a Russian agent. She saw not only the old agents and the young agents who had trained with her back then, but also her kidnapped husband. It turned out that it was the old spy who doubted Sauter's loyalty, so he seized his husband to threaten Sauter to do something for them. But Sauter still estimated that the former instructor was wrong. The old agent cruelly drowned her husband in a water jail in front of Sauter.
Sauter, who was extremely sad in his heart, resisted the pain and put on an indifferent expression in front of the old spy and the spy classmates, but in his heart he hated these people who killed the man she loved. She set out the next step of the old agent-assassinating the President of the United States to start a world war. Later, while the other party relaxed his vigilance against her, he killed the old spies and all the former Soviet spies who were present.
After that, Sauter contacted the contact person for the old spy’s next plan, an Eastern European colonel. Looking at the scar on the general's face, Sauter remembered that he was his best friend at the Junior Secret Service School. This best friend of the year still trusts Schott very much, and he tells Schott completely about his plan. So in one evening, the colonel brought Schott, who had become an officer in civilian clothes, to the White House to attend a diplomatic banquet. However, Sauter's former boss discovered Sauter's trace and immediately arranged for the president to evacuate. The colonel tried to kill the President by detonating his explosives, but ultimately failed. Sauter watched the worthless death of his once best friend, unwilling to reconcile, so he lifted his disguise and continued to hunt down the president and his party.
Sauter’s boss in the CIA took the president and his party into the underground shelter of the White House. However, the horrified group discovered that Sauter’s former CIA boss had raised a gun at him. This true identity was even more than Sauter’s. The Russian agents who had to lurk in the CIA early killed everyone except the president and forced the president to launch a nuclear bomb to really cause a world war. After a fierce fight with his former boss, Sauter was eventually taken away by soldiers who came to support the president. But his former boss claimed to be a protector of the president, covering up the truth that he was a Russian agent.
Seeing his former boss's still shameless face, Sauter finally suffered a killer when he was taken away, strangling to death the former boss who was planning to kill Sauter at the time to protect his secret.
On the way to the escort, the black colleague who had suspected Sauter asked her, how many agents like her still have? Sauter replied that people like me are dead, and there are countless others like him (Sauter's former boss, a group of Soviet agents who were trained as juvenile agents earlier than her). In the end, the black colleague secretly let Sauter go.
