- Lies in ashes are more burning than fire
When the century-old theater was turned into a sea of flames during the singing of "Lin Suo", the criminal investigation team leader Lu Chenzhou pulled out a ball fan with blue background and gold thread between the fingers of the scorched corpse. The deceased was Peking Opera master Cheng Yunsheng, but the autopsy showed that the scar on the right hand of the 63-year-old body completely overlapped with the birthmark on the arm of the missing adopted daughter Cheng Xuesheng.
Three minutes were strangely missing from the fire surveillance video, and the clavicle of "Cheng Xuesheng" who claimed to have survived was embroidered with the missing plum blossom brand on the round fan - the death mark of the military reunification stakeout twenty years ago. During Lu Chenzhou's investigation, he discovered that there was a microfilm hidden in the jade hairpin collected by Cheng Yunsheng, which recorded a list of spies that matched the fingerprints of high-level officials in the public security system.
The deadliest chant sounded on the seventh night. The "resurrected" Cheng Yunsheng in the morgue took off his mask, revealing the same face as Cheng Xuesheng - they were mirror people cultivated by the military's "Twin Butterfly Project". When Lu Chenzhou opened the secret door of the stage with a blood-stained pocket watch, the old dean was painting facial makeup on the real Cheng Yunsheng's body, and Cheng Xuesheng's gun was already aimed at his heart...
In this life-and-death situation that spans twenty years, every libretto is a code and every costume is stained with human blood. When Lu Chenzhou finally deciphered the Morse code in his pocket watch, he discovered the cruelest truth: every movement of Cheng Xuesheng's eyes was a calculated killing move; and the most deadly secret is always hidden in the tone of the play.
