Codename: Bone Butterfly

A young woman's body is pulled from a cold riverbank. The police's preliminary conclusion: accidental drowning. When the victim's twin sister, the sharp and composed forensic pathologist Ye Shuyun, touches the body that looks so much like her own, professional instinct cuts through her grief in an instant: abnormal fluid in the lungs, a hidden needle mark, a missing kidney... This was no accident! The victim was her younger sister, Ye Shuya, an investigative journalist determined to expose society's dark side. While sorting through her belongings, Shuyun discovers the unfinished investigation her sister left behind: a vast underground organ-trafficking network codenamed “Bone Butterfly,” whose reach is quietly extending into several of the city's most prestigious hospitals, especially the celebrated De Kang Hospital. Her sister's encrypted notes are filled with clues about the mysterious disappearances of the poor, traces of illegal deals, and a bizarre butterfly emblem. Shuyun's questions meet with cold resistance. The hospital is tight-lipped, while senior police officials call the matter “sensitive” and urge her to close the case. On the pendant her sister left behind, the bone-like imprint of a butterfly seems to mock her in silence. She resolutely casts aside her forensic composure and steps alone into the abyss her sister laid bare with her life. Using her expertise, she dissects the lies, tracks the missing “donors,” and infiltrates the restricted areas beneath De Kang Hospital's polished exterior.
