Chen Mo's family, who received a new apartment from relocation and demolition, was approached by Wang Cuihua, a tenant who had rented their old house for ten years, demanding half of the property. After her demand was refused, Wang Cuihua harbored malicious intentions: in the middle of the night, she released a venomous snake to bite Chen Mo's eight-year-old daughter, Mengmeng, and repeatedly terrorized the child with a simulated toy snake. With the community surveillance missing, the villain exploited loopholes in the evidence. Chen Mo no longer compromised, secretly setting up surveillance to completely record all evidence of Wang Cuihua's extortion, unauthorized occupation of the hallway disturbing residents, and illegal electricity use causing a fire. Facing moral kidnapping and public misunderstanding from neighbors, Chen Mo held all the evidence and resorted to the law. The villainous Wang Cuihua was ultimately sentenced to fifteen years in prison for multiple crimes.
