Chen Yuan, who opened a new cold storage facility, refuses a request late at night from merchant Wu Yongfa who wants to store goods temporarily for free. Wu Yongfa's goods experience abnormal temperature control during transport, but he deliberately alters registration records, frames the cold storage for damaging the goods, and tries to use benefits to bribe Chen Yuan into forging warehousing documents in order to shift the risk. Facing market rumors, cooperation crises, and all sorts of harassment from the other party, Chen Yuan adheres strictly to warehousing procedures, preserves complete monitoring and data evidence, clarifies responsibility and right from wrong, and ultimately defends his principles while figuring out the business path for short-term storage.
