In order to find his father who disappeared on a scientific research ship 20 years ago, Lin Shen, a 26-year-old antique restorer, landed on the island with a map of Kirishima left by his late mother. His companions included Mrs. Kiri who wore a bronze mask, the mysterious doctor Cheng Ye, and the twin sisters wearing pocket watches with photos from 30 years ago. Kirishima devours ships every 20 years and initiates the "seven-day cycle of death". All living people on the island have fatal "fog reflections".
After landing on the island, the "Morning Star" that sank 20 years ago reappeared. His father's notes revealed that he was the "key" to the 13th reincarnation, and Mrs. Fog was actually the elderly version of his girlfriend Su Qing - she was reduced to a "half-fog core" due to touching the reflection. When the three layers of time and space overlapped and the mirror curse escalated, Lin Shen discovered that he was actually the 13th reincarnation of the island owner a hundred years ago. Cheng Ye, on behalf of the island consciousness, forced him to kill his companions and become the new island owner.
Holding a bronze dagger engraved with 12 notches, Lin Shen faced the choice of piercing the reflection and causing the island to collapse, or accepting his fate. Su Qing's warning echoed when the fog cleared, and the "Fog Researchers" outside the island were planning to use nuclear bombs to end reincarnation. The truth of the 13th Dawn was hidden in the cracks in the mirror and memory...
