The down-and-out Li Rui unexpectedly is reborn, just as his family falls into hardship, and awakens the catch perspective system. Carrying the wish to protect his wife and daughter, he relies on his perspective ability and special fishing gear to go tide-pegging and fishing, harvesting prized seafood one after another. After making a modest start, he attracts harassment from peers and neighbors, and his mother-in-law also frequently comes knocking to make demands. Joining hands with partners to connect with high-end restaurants, acquiring fishing boats to form a fleet, Li Rui faces overseas fishing competitors head-on, seizes the opportunity to protect his family, and opens up a brand-new life.
