In the midsummer of Jiangcheng in 2019, the rancid smell of Hepingli Community broke the tranquility. The unusual smell in Room 301 involves the mystery of the corpse. Under the guise of decoration, it is a trap carefully laid by the murderer. The coerced Wang Hao, the missing Zhang Min, and the mysterious Lin Xinzhe, everyone wears a mask and plots against each other in a chess game of desire and hatred.
Expired plastic wrap accelerates the exposure of rottenness, hollow bricks hide corpses, anonymous USB flash drives, and jade pendants with the word "Li". The clues are intertwined; police undercovers, illegitimate children's revenge, rare disease coercion, and reversals are staged one after another. When the false identity is exposed, family affection and betrayal collide, the seemingly perfect criminal plan finally falls apart due to the flaw in the human heart.
This dark game in which everyone is involved hides the persistence of justice and the desire for redemption. The rotten smell has dissipated, and the old building has been reborn, but those tortures about human nature, crime and punishment are still shocking when the truth is revealed.
