Stay-at-home dad Shen Qiyuan, in order to save his kidnapped daughter Lele, transformed into a top hacker and started a three-hour countdown to life and death in his wife Lu Qingyue's company. He used the exposure of everyone's privacy as a bargaining chip to force him to find his daughter, but his wife favored his male secretary Xu Mingyu and was humiliated and accused by the entire company. During the countdown, he uncovered the truth layer by layer: he had committed financial fraud, misappropriated the couple's common property during marriage to support his lover, and the child he cared for so carefully was not his biological child. Xu Mingyu jumped over the wall and revealed that Lele was hidden in the freezer. Fortunately, the child had already rescued himself. The bad guys will eventually reap the consequences, Xu Mingyu has no chance, and Lu Qingyue is imprisoned.
