Three years ago, war reporter Lin Xuezhao was publicly regretted by her fiancé Lu Yanting on the eve of her wedding. The family business went bankrupt overnight and her father died mysteriously. Three years later, she returned home with honor as a recipient of the Peacekeeping Medal, only to discover that her father's death was inextricably linked to the Lu family. In order to find out the truth, she changed her name to "Lin Zhao" and pretended to be a docile and harmless orphan. Through a family marriage, she married again the man who ruined her family. She thought this was a forbearing revenge, but she didn't know that Lu Yanting was also using her marriage as a pretext to secretly investigate a mysterious force that threatened her life. When the evidence she collected gradually pointed to him as the culprit, she discovered that behind all his suspicious behaviors was the ultimate guardian who used his life to deal with evil. When the truth came to light, she took off her disguise and stood side by side with him in a dazzling manner to liquidate all the sins together.
