Eight-year-old girl Jiang Chuyan witnessed an explosion in the crematorium on the day her father Jiang Wanhao was executed for a smuggling case, leaving her with only ashes. Detective Rao Yuan discovered that Chu Rui, the surviving corpse cremator, had lost his memory and was disfigured, and the case of his wife and daughter remained a mystery. After her mother died of illness, Chu Yan struggled to survive amid suspicions about her uncle Zhang Yiyang's sudden wealth and school bullying. Ten years later, Zhang Yiyang's father's tombstone was stained with the blood of a black dog. Zhang Yiyang died violently after robbing the tomb, revealing the truth about Jiang Wanhao's death. He was shot at the execution ground but was not fatal. During the explosion, his identity was switched with that of the corpse cremator Chu Rui. Due to the trauma, his dual personality was split: he lived in confusion during the day and cursed his own tombstone late at night.
The "P-shaped" cultural relics left by Bian An, the leader of transnational smuggling, triggered a conspiracy. Yang Hankong, the father of Xiao Jing, an autistic student, was actually the mastermind behind Jiang Wanhao's murder ten years ago; his aunt Liu Xin took advantage of the funeral to conspire with Yang Hankong, exposing his identity as a double agent. Bian An's son kidnapped Chu Yan, triggering a shootout. The police used her earrings to locate and close the net. During the melee, Jiang Wanhao was shot to death while trying to save his daughter, and his suicide note was burned into a gray butterfly. Chu Yan burned the relics to end the nightmare, turned over the cultural relics guarded by Zhang Yiyang, and brought Yang Hankong and Bian An to justice.
The bloody mystery began with the greed of two generations and ended with rebirth from the ashes. The misplaced identity and blood curse dissipated with the flames, and the girl cultivated the power to break out of the cocoon in the ruins of sin.
Purpose: Through the mystery of identity in the embers of crime, explore the redemption of human nature under the bloody fate. Using the ruins of lies as a mirror, it reflects the self-tearing and reconstruction of the sinful bloodline, revealing the truth of father's love struggling in identity dislocation and memory cracks, and finally tempering the ashes to transcend the shackles of blood.
