A conspiracy, a cruise ship that will never reach the shore, and two young people who met on the sea.
Li Qianshi embarked on his sea journey, but fell into a deep crisis. He and others on the ship faced the threat of being buried in the sea.
Shen Fei from the mermaid tribe came to the rescue, and a spark of love arose in this battle for survival with Li Qianshi.
Facing the endless sea and the unknown future, it is courage that keeps them moving forward, and it is love that makes them rely on each other.
When the light of hope illuminates the dark night, there will be another brilliant sunrise on the horizon.
