Twenty years ago, Wang Da and Wang Xiao cheated Old Shun Tou out of 3,000 yuan. Today, at Wang Xiao's birthday banquet, the mistaken delivery of beef rice noodles reignites an old grudge. Shun Shui infiltrates Tianchuang Culture as an undercover operative and foils Shuntian's scheme to force Shunfeng to sign a mortgage contract. During preparations for a trade fair, the truth about their identities is revealed: the four siblings are biological siblings, and Wang Xiao caused the death of his biological father. After the net closes, Shuntian is arrested, while Wang Xiao flees abroad with Shundi and uses AI face-swapping technology to stage a virtual kidnapping. The authorities establish a special task force named King Bomb. Shun Shui leads the team across borders to capture Chen Youliang, and Wang Xiao is sentenced to life imprisonment. Shuntian repents, the siblings reunite, and the fight against fraud continues.
