Zhang Feiyan, a modern‑day coastal‑hunting internet celebrity, transmigrates to the 1980s as the feared “mad girl” in a fishing village. The handsome Su Jingchuan, whom the original host married by draining the family savings, absconds with the money. When Zhang Feiyan goes to demand repayment, she falls for Su Wenyan, Su’s second son — a beautiful yet consumptive young man — and makes him marry into her family in his brother’s place. Drawing on modern tide‑pool foraging know‑how and her robust physique, she climbs from rags to riches to become the village’s wealthiest. She dotes on her frail husband, gets revenge on her former suitor, and lifts the whole village to prosperity.
