1978, Fishing village in southern Taiwan. Eighteen-year-old Shen Yulian grew up on thin ice in the home of her adoptive parents. The secret of her biological mother's early death shrouded her life experience like fog on the seaside. Her only warmth comes from her childhood sweetheart, the fisherman's son - but that is not love. The person who really broke into her life was Zhou Shi'an, an urban youth who came to the fishing village during the summer vacation. The collision of two worlds is like waves hitting a rock, and the waves stirred up are destined to break.
