Set in a fishing village in the 1980s, Holt Carter is reborn with memories of his past life where his wife and daughter died tragically and he lived a destitute, failed life. Right after waking up, he catches his father and elder brother trying to seize his leg treatment money to pay off the Eldest Son's gambling debts. He immediately cuts ties and initiates a Family Division, leaving the household with nothing but a run-down shack on a desolate stretch of Rocky Cove that everyone despises. Relying on his Tide Foraging skills and aquaculture insight, he harvests sea cucumbers, builds fishing rafts, farms clams and kelp, secures long-term orders from county restaurants and the Fisheries Station, and transforms the barren beach into a thriving aquaculture base. The greedy relatives who come to curry favor later are soundly humiliated, and Holt Carter builds a prosperous, stable life for his wife and daughter at Rocky Cove.
