Maintenance worker Lin Chuan comes to fix the air conditioner. Eighty yuan is the platform's clear and stated price. As soon as the job is done, he encounters a trap carefully set by the homeowner colluding with others. Being secretly filmed with edited videos and rumors spread in the homeowner group, his platform account gets risk-controlled and suspended, and his livelihood is in imminent peril. He does not swallow his anger, gathering chat records, original footage, human witnesses, and material evidence. From a confrontation in the hallway to a livestreamed public showdown, he tears open a fake rights-protection routine in the residential compound that victimizes door-to-door laborers, fighting desperately to win back his reputation.
