In a Minnan fishing village in the 1980s, young woman Lin Wan bore huge debts due to her father's passing, and her family's old house was nearly mortgaged off. In a desperate situation, she resolved to take root in the mudflats and carve out a path to survival through aquaculture. Facing ridicule and doubt from the whole village, repeated harassment by local tyrant Wang Haiba, and aggressive acquisition and suppression by external capital, Lin Wan did not back down. Utilizing her notebook experiences and combining practical techniques explored on the ground, she solved severe natural disasters and crises such as water deterioration, soil hardening, rainstorms and high temperatures, and red tides. The aloof top student Chen Yu was moved by her tenacity and lent a helping hand all the way. The two joined hands to break through internal and external troubles, resolve capital monopoly, and finally got married and achieved a career of their own.
