Truck driver Cheng Lidong partners with his childhood friend Shao Kai to haul freight, agreeing to split the profits equally. After earning a net profit of 1.97 million yuan over the year, Cheng Lidong receives only 100,000 yuan. Shao Kai refuses to honor their profit-sharing agreement, claiming that the truck belongs to him. Using that money as a down payment, Cheng Lidong takes on a 420,000-yuan loan to buy his own truck and build a business independently. On New Year's Eve, Shao Kai publicly dismisses his earnings as a mere red envelope. Cheng Lidong sets the record straight in front of everyone, comes clean to his family, and officially ends their partnership. From then on, Cheng Lidong runs his equipment transportation business with integrity, gradually repays his debts, builds his own fleet, and marries Song Jianing. Meanwhile, Shao Kai's reluctance to spend money on vehicle maintenance and workers leads to mounting losses and the departure of his customers, until his business collapses completely.
