On the day of the divorce, Jiang Yan received surveillance from his ex-wife Shen Zhao - the 'corpse' he had buried with his own hands slowly raised his hand in the coffin. In the murder that shocked the whole city three years ago, he thought he had ended his nightmare, but he didn't know that what he buried was not a corpse, but a time bomb that detonated the abyss. Su Ling's experiment, Chen Huai's lies, Lao Zhou's silence and Lin Xiaoman's secret recording are all intertwined into a web that swallows the truth. When the memory of the 'dead' begins to revive, Jiang Yan must choose between justice and redemption whether to continue to bury the past or to dig up hell with his own hands.
