Orphan Sang Yaya saves the teenager Sang Wangye on the beach and is kindly adopted by the impoverished Sang family. She can sense the hints of the spirits in the seaside mountains and forests, helping her family avoid danger and survive. Facing neighborly disputes and malicious suppression by businessmen, the Sang family upholds their original intentions and does not covet unjust wealth. The whole village looks out for one another, joins hands to fight disasters, builds a mountain and sea market together, and sets up a rural school. After enduring tests such as the turmoil of recognizing relatives and rescuing marine spirits, Sang Yaya officially settles in the Sang family. Everyone in the little fishing village is of one heart toward kindness, and relying on hard work and fairness, they usher in a stable and beautiful new life.
