In a seaside fishing village, the Zhao family has used its power to bully the Lin family for generations, encroaching on the Lin family's aquaculture waters and building their longevity tomb directly on top of the Lin family's ancestral graves. Lin Wanzhou, who has returned from studying abroad, refuses to back down any longer and applies to convert her family's ancestral home into a marine waste transfer station. When the Zhao family patriarch dies, his family has no choice but to ask to borrow the Lin family's pier for the funeral procession. Lin Wanzhou publicly settles old scores, forcing the Zhao family to remove the tomb and return the occupied sea area. In the end, the wicked Zhao brothers suffer the consequences of their own misdeeds.
