The unsolved cases of the Republic of China turned into life-threatening bone bells, and the bloody afterimages were locked in a century-old contract. Criminal investigation consultant Shen Zhaozhao's psychic ability completely went out of control when she came into contact with the key evidence of the serial murder case - the bone bells clenched in the hands of the three corpses, which actually allowed her to glimpse an unsolved massacre in the 26th year of the Republic of China: a bride wearing a floral skirt was shot to death indiscriminately, and the bloody Browning gun handle was engraved with a lotus pattern.
When she followed the guidance of the bone bell and broke into the "Bone Bell Zhai", an antique store in the deep alley, the mysterious shopkeeper Gu Qing let her wrist wear an jade safety buckle with the same cracks as her mother's relics. What's even more shocking is that in the old yellowing photos on the wall, the bride from the bloody wedding had a cinnabar mole on her collarbone that completely coincided with her birthmark; and the groom holding a gun clearly had the face of Gu Qingrang!
In order to break the life-demanding contract that spanned a century, Shen Zhaozhao was forced to become the 100th "contractor". When the bone bell rang, the memories of her past life surged back to life: the overlapping gunshot wounds in the heart, the crisp sound of the safety buckle breaking, and the marriage vows that were lost in the flames of war... When the antique shop turned into a contract prison that devoured the living, she discovered that all the dead were the reincarnations of people related to the tragedy of the Republic of China.
The murderer in this life is using a Browning pistol to re-enact the massacre of the past. The lotus pattern on the handle of the gun and the Sanskrit bone bells bite into each other to form a deadly formation. Shen Zhaozhao must make a decision before the next bone bell rings: destroy the contract and release Gu Qing's soul that has been imprisoned for centuries, or let the souls of the Republic of China be reborn and wreak havoc on the world through the bone bell? And the Browning that decided the outcome was held in the hand that pulled the trigger in her previous life...
