Su Wanqing paid 150,000 yuan for a privately owned parking space, only to have Wang Guixiang occupy it every day with a little folding stool. Whenever the police arrived, Wang would clutch her chest and pretend to be ill, then turn around and demand that Su pay her 800 yuan a month in parking fees. After eight years working in intelligent security systems, Su decides to stop arguing. She spends 100,000 yuan of her own money installing a fully automated enclosure system around the parking space, complete with three voice warnings before the barrier comes down, and takes leave to visit the grasslands. Wang moves in a folding bed and smashes the surveillance cameras, only to get locked inside overnight. When she finally gets out, she demands 500,000 yuan. Su signs a 200,000-yuan compensation agreement, but Wang joins forces with her children to fabricate a severe injury assessment and file a countersuit. In court, the torn-up warning notice, backup surveillance footage, and original medical records are brought out one by one, exposing the truth. All four members of Wang's family are sentenced to prison.
