In a city cloaked in fear, Special Agent Shirley, with her striking silver hair and ever-present red scarf, hunts a serial killer known only as 'The Angel of Death.' This elusive murderer leaves no trace, only a chilling signature: a heart removed, a phrase painted in blood, and an escalating brutality that now targets children. Shirley, herself a survivor of a childhood brush with death, possesses an uncanny ability to reconstruct crime scenes, a gift that borders on the supernatural. But as the lines between reality and the bizarre blur, and a new partner tests her limits, Shirley must confront not only the darkness within the city but also the unsettling secrets within herself. Is her unique gift a blessing or a terrifying link to the very evil she hunts?
