Lin Zhou woke up on an isolated island shrouded in thick fog and lost all his memory. Accompanying him were only a mysterious man named "Chen" and a watch that stopped at 3:14. The island seems to have its own rules, the tides wash away fragments of memory, and every storm heralds a revelation of the truth. In order to find himself, Lin Zhou must piece together his past life on this isolated island that is both a prison and a shelter. But he soon discovered that the biggest enemy was not forgetfulness, but the cruel truth buried deep under the sea of memory that he dared not face. What he wants to retrieve may be what he desperately wants to forget.
