On a night of torrential rain, a death invitation from “Night Owl” drags Cheng Mo, a former criminal investigation expert who has lived in seclusion for five years, back into a blood-soaked vortex. In an abandoned church, a wealthy man is nailed to a cross, the Latin word for “greed” carved into his forehead. Atop an ancient bell tower, a food-industry tycoon is disemboweled and hung upside down, marked with the sin of “gluttony.” The killer takes the Seven Deadly Sins as a blueprint, recreating crime scenes from Cheng Mo’s sealed-away old cases and leaving behind a blood-written puzzle pointing to his father’s unsolved Seven Deadly Sins case from twenty years ago.
Forced to work with police captain Lin Xia, Cheng Mo is stunned to discover that every victim is connected to a mysterious “Starlight Fund.” A blacked-out group photo, a newspaper clipping from five years ago, a silver coin left by his father... Every clue weaves into a vast web, with Cheng Mo himself at its very center. When his hacker niece Cheng Xiaoyu is kidnapped and his adoptive brother Zhou Zheng produces a bloodstained paternity test, Cheng Mo finally learns the truth: twenty years ago, his father concealed a deadly secret, plunging two generations into a cycle of sin.
