An old pocket watch engraved with exotic patterns brings retired military doctor Wen Hua into a bizarre dilemma.
He mistakenly entered a mansion with an ever-changing structure. The space folded repeatedly, and the surrounding scenes were difficult to distinguish between reality and reality. He was trapped in an endless cycle of puzzles and could not escape.
Concession detective Huo Ming noticed something unusual and came to the rescue despite the rain. Knowing that this ancient watch would bring successive troubles, he resolutely took the item and shouldered all the problems alone.
In trouble, the two supported each other. The original intention of breaking into layers of puzzles was always to protect each other and return to a stable daily life together.
Intention: I am willing to bear the suffering of the world for the one I love.
