"We are each other's prison and our only antidote."
In the late-night anatomy room of the medical school, Ji Fei reunited with his younger brother Ji Wu, who had disappeared for three years. The rusty collar and blood-stained butterfly specimens revealed the secrets of genetic experiments buried by the family. The thorn-shaped scar on Ji Wu's neck and the mysterious healing factor in Ji Fei's blood push them into the forbidden abyss.
When paranoid possessiveness intersects with a pathological symbiotic relationship, the bloody tattoos at the engagement party, the private collections in the darkroom, and the living specimens in the basement all tell the truth: from the day the family used them as "symbiont" experiments, their fate was destined to rot in the thorns and coexist in the darkness.
Do you think it's salvation? No, this is a fatal entanglement that begins with blood and ends with destruction.
