Lin Qiu, a 28-year-old delivery worker, discovered that he could see memories when he touched objects. The butterfly birthmark on the back of his neck was the key to the "time gene" that the Black Moon Organization had been pursuing for twenty years. And the daughter Duoduo, who suffers from heart disease, has the same light red mark on her palm, which is actually the core of starting the genetic experiment-her heart hides the other half of the time gene that her mother split back then.
The mysterious nurse Su Wanqing breaks into life, and the silver butterfly tattoo under the mechanical prosthesis brings out the twenty-year confrontation between Dawn Organization and Black Moon. When the death scene in the villa's bathtub, the corpse in the freezer of the pet hospital, and the hospital director's butterfly brooch were connected in a network, Lin Qiu was shocked to realize that every time she used the superpower, Duoduo's heart failure would be accelerated. A more cruel truth was revealed: Duoduo was not his biological sister, but his biological daughter "conceived" through genetic technology. Their genes were the twin keys for Black Moon to create the "time beacon".
Black Moon's mirror army attacks with clones, and at the moment when twelve silver butterfly hairpins piece together a time beacon, Lin Qiu must use the ability to "look back in time" to solve the mystery of the twenty-year experiment. The mother's "gift of time is not a blessing" before her death will eventually be revealed in the ripples of time when father and daughter touch each other, and the ultimate answer to the question of protection and sacrifice behind the twin butterfly shadows will be revealed.
