The film itself is not brain-burning, and the connection between the two parts is very clear. In the first half, agent Max obtained the identity of undercover Marianne's husband, and the two worked together to complete the mission of assassinating the German ambassador and successfully escaped from the hail of bullets. The two also pretended to fall in love and gave birth to a daughter during a German plane bombing. In the second half, the style changes. When Marianne is suspected of being a German spy, Max falls into entanglement and pain. He needs to find out her true identity and try to prove that his wife is not a spy. However, the result was cruel. The film was interrupted. Before Max and Marianne got married, Max's leader said "Marriage in war is destined not to last long" which already foreshadowed the tragic ending. But true love in the flames of war is truly great. . Max's plan to elope with Marianne is the best interpretation of Xiao Ai. In the war environment, his choice is to escape the war for his family, even if he has to be charged with treason; Marianne's shocking shot in order to protect Max It is a perfect interpretation of great love. For the person she loves, she is willing to sacrifice herself to save her husband and her family. The deep love is life and death. For love and family, women's sacrifices are different from men's, but they are equally great and moving. During the war, two people who love each other may not be able to stay together for life because of differences in beliefs, regions, or various reasons. For them, war is cruel, and love is an upgraded version of cruelty. "Spies" directly displays this contradiction to inspire people's softest sadness.

When love conflicts with national interests and national interests, we always think that killing relatives for justice is cruel but must be done. But if we really put ourselves into it, how many people can really do it?
