For three months, office worker Tang Wei lets her male colleague Han Bin hitch rides in her car. He never pays a cent and constantly complains about everything. Having finally had enough, she sells her car and switches to an electric scooter. But Han Bin holds a grudge. He forges an authorization letter to fraudulently retrieve her already-sold car from the dealership. After causing a traffic accident, he tries to shift the blame onto Tang Wei. Facing threats and false accusations, Tang Wei fights back step by step using preserved chat records, contracts, surveillance footage, and other evidence, ultimately ensuring that Han Bin and his accomplices face legal consequences.
