Shen Shuai accidentally discovers that his wife Su Man knows Zhou Ze—and that his sister-in-law Su Tang knows Zhou Ze too. Consumed by resentment, Shen Shuai meets Zhou Ze's wife, Gu Wanning, and the two form an alliance. Shen Shuai storms into the house time and again, while the Su sisters keep hiding Zhou Ze and spinning lies to cover their tracks, setting off one farcical scene after another—a rooftop dinner, a house search, and more. Gu Wanning designs an investment project and coaxes Su Man and Zhou Ze into sinking their entire fortunes into it—only for the investment to fail. In the end, the two turn on each other, blaming and beating one another. They get exactly the punishment they deserve.
