Haining unexpectedly arrives at Baisha Village, a coastal settlement, where the kind-hearted Shen family welcomes her. Gifted with the ability to sense the tides and marine life, she discovers that the tidal channels outside the village are gradually losing their vitality. Determined to protect her new home, Haining joins forces with the Shen family to restore the channels, protect young fish, and rebuild the pearl farms. Through one storm after another, they uncover the reason behind the decline of the surrounding waters. In the end, two coastal villages put aside their differences and work together to find a new way to live in harmony with the sea.
