Chen Zheng, the owner of a three-crown digital electronics store, sells a top-of-the-line RTX 4090 graphics card, only to be deliberately scammed by a college student who returns a red brick instead. Thanks to the platform's instant refund policy, the money is transferred back to the buyer immediately, who even arrogantly challenges Chen Zheng to pursue legal action across provincial borders. Unwilling to swallow this humiliation, Chen Zheng jumps on his motorcycle and races 1,500 kilometers across provinces to track down the culprit. Carrying the red brick, he storms straight into the student's dormitory, exposes his repeated scams layer by layer, and ultimately makes the offender pay a devastating price: expulsion from university and imprisonment.
