"Welcome to the Mad Bone Trial, your bones are your last currency."
When a strange game called "Trial House" comes, Wenren Zhuming gets involved in the search for his sister who has been missing for many years. Here, the boundary between reality and fantasy is completely crushed, and participants use their own "bones" as bets to survive in a world of countless twisted rules. In the ancient house where "you cannot stare at the person in the mirror", she met an unexpected figure - Yan Hui, her ex-girlfriend whom she had spent her entire youth loving and hated with her deepest despair.
Yan Hui looked distant, as if he had never made peace. They are forced to become partners. In the weird rules and regulations on the front line of life and death, one is calm and rational, and understands everything; the other is crazy and paranoid, and breaks the situation with his life. As trust and betrayal are repeatedly tempered in blood, the hidden past and the truth of the "Trial House" gradually emerge. Wenren Zhuming discovered that Yan Hui's forgetfulness might be a carefully planned redemption, and her sister's disappearance was actually closely connected to the core of the game's origin...
The cunning judge Yu Jing, the teammate Jiang Jinyue whose identity is a mystery, and the friend and foe Xie Yuxi appear one after another. On the edge of madness and reason, they must answer: When the one they love becomes the "rule" itself for passing the level, should they follow the systematic "trial" or follow the "crazy bone" in their hearts?
