Shen Qi, an urban chess player known for his calmness, received an unknown invitation in the cracks of fate: go to the "Jinglan Island" hanging on the lonely sea to participate in a gambling game that only allows losers to enter. There are constant storms on the island, and the strange rocks are like a maze. The islanders are hidden behind masks. It seems that everyone has lost a corner of their soul in the bet. The bargaining chip in the gamble is memory. The winner can reinvent himself, while the loser will be lost forever. Shen Qi wanted to escape the predicament of life, but found that every step was guided by unknown rules. The island itself seemed to have consciousness, inducing participants to reveal their innermost secrets. The mysterious witch on the island, the mute sailor, and the lying beach are all testing his faith. The final bet is actually related to the survival of the island and Shen Qi's own choice: bet on the final truth, or protect the ashes in his heart? In this land where tides and mysteries intersect, Shen Qi must bet his soul to find his own way back.
