In 1989, Lin Yu travels back in time to the year before his father, Lin Jianguo, reaches a turning point in his fate, and moves into the Lin family home under the identity of a distant cousin's nephew. Facing his father's timidity, the eldest branch of the family making things difficult for them, and the factory's layoff list, Lin Yu starts by collecting and reselling goods. From going door to door to opening a purchasing depot, he helps his father carve out a way to survive, step by step, while bringing the whole family together from distant onlookers into a united front. His father goes from never daring to imagine it to saying, "I want to give it my best, too."
