In 1980s Heguk Gu, driver Luo Funian goes missing after a landslide for half a year, leaving behind a damaged small truck and oil debts. The creditor sets a three-day deadline to pay the down payment, or else the truck will be towed as debt repayment. Repairman Cheng Yuanshan comes over through a matchmaker, meticulously repairs the brakes and truck bed, and makes a living hauling goods with household head eldest sister Luo Qiuning and younger sister Xiaohua. Withstanding merchants cutting prices, rainy leaks, and the temptation of overloading, they keep clear accounts, bear their own cargo damage, gather the down payment, pay off old debts month by month, and find their missing father, forging a transport team and fixing up an old truck as well as building a home.
