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 barges into the house time and again, while the Su sisters keep hiding Zhou Ze and spinning lies to cover it up, setting off one farce after another—a rooftop dinner, a house search, and more. Gu Wanning designs an investment scheme that lures Su Man and Zhou Ze into pouring in their entire fortunes, only for the investment to fail. In the end, the two turn on each other, blaming and beating one another. They get the punishment they deserve.
