Agent Sauter I feel a little confused, can anyone tell me?

In fact, he was a Russian spy, but he was forced by the Russian side to kill his parents and husband, and the U.S. Embassy took him in and gave him a job and life. In the face of love and hate, he chose to love him. The country kills the people it hates. This is an ancient Chinese martial arts revenge story. When you know all the truth, you will make the right choice. This film shows how ugly the fraternity in the United States is and how Russia used love to influence a true man. The enemy spy film also shows at the end that the philanthropic President of the United States woke up and knew everything. There was no need to escape, but he still quietly let him go. According to the law, the official who let him go was killed.
