Qin Yao raises her four-year-old daughter alone. Late at night, the child has a high fever of forty degrees, and rich second-generation Ye Cheng's sports car blocks the only exit of her home. Qin Yao begs him to move the car, is met with a cold refusal and phone shutdown, and the child nearly suffers a febrile convulsion. After the child recovers, Qin Yao builds a wall within her legally owned property and plants scientific research saplings valued at four million five hundred thousand to defend her rights. Ye Cheng returns and is furious with embarrassment. Through judicial trial, Ye Cheng constitutes the crime of intentional destruction of property, is sentenced to four years in prison, and must compensate for the losses in full. Finally, Ye Cheng makes a public apology and fulfills the compensation, and Qin Yao defends her dignity and her family's safety.
