Fifteen years ago, the island of Peace and its residents disappeared in the midst of a powerful typhoon. Local people connect this event with the appearance of a mythical creature from ancient Chinese tales.
The only survivor known was a young Shen Ko, who that night was staying with his grandmother on a neighboring island of Joy. However, a recent find in the sea changed that assumption: another resident of the vanished island had been saved—someone who disappeared fifteen years ago.
Surprised by this discovery, Shen Ko decides to pause his participation in the final of an international chess tournament and returns to the places where his childhood passed. He has only three days to meet the memories of the past and find out the fate of his loved ones. Upon arrival on the island of Joy, mysterious deaths begin to happen.
