On an isolated island at the end of the world, stands a lighthouse that never goes out. Lin Mo, the young tower keeper, inherited the family's destiny and guarded an unknown secret: the light of the lighthouse did not guide ships, but suppressed a strange route to the "Lost Land". This route will materialize the intruder's deepest desires and swallow them up forever. When the persistent map surveyor Su Lan followed the broken clues and landed on the island in search of her missing brother, the fate of the two people began to intertwine. Lin Mo's dusty past and Su Lan's desperate pursuit jointly opened the illusory door to desire and destruction. What they will face is not only the strange phantom on the route, but also the most fragile reflection deep in their own hearts.
