58-year-old Silkworm King River Lowe spent all his savings to buy a house and arrange a marriage for his son, only to be humiliated and driven out of the home by his daughter-in-law Wang Yue. He returns to Whitewater Village, relying on 30 years of silkworm rearing expertise, starting from an abandoned silkworm rearing house. He rescues sick silkworms, collects wild mountain produce, expands the silkworm factory, and works his way up to win the National Silkworm Rearing Competition championship, taking home a 5 million yuan prize. His son's family, who owe 5 million yuan after an investment crash, come back to beg for help. River Lowe sticks to his principles and refuses to bail them out. Eventually, the son and his wife work to pay off their debts and sincerely repent.
