Lu Yuan single-handedly built the cold-chain delivery network for Wanjia Fresh. However, his business partner, Zhao Qiming, teams up with his girlfriend, Cheng Xiaomin, to seize the refrigerated truck fleet and force Lu Yuan out of the company with its debts. Ignoring professional cold-chain standards, Zhao Qiming recklessly adjusts temperature controls and mixes different types of cargo, causing two entire shipments of fresh produce to spoil and costing the company its major client. After realizing Zhao Qiming's selfish nature, Cheng Xiaomin tries to win Lu Yuan back, but he has decided to leave the past behind. Starting over with an old van and carefully managed deliveries, Lu Yuan earns the trust of fruit grower Lin Xiaoman and secures a major premium cherry order through his expertise. After successfully fulfilling the contract, he establishes a long-term partnership with Wanjia Fresh, repays his debts, and launches his own cold-chain logistics company.
