Freshman college student Huo Ke possesses a special superpower enabling her to hear various objects speak. On her way to school, through a meat grinder's accusations, she exposes a shocking murder case where a breakfast shop owner kills people to make meat stuffing. Afterwards, relying on the inner voices of items such as a pearl hairclip and a watch, she successively cracks multiple difficult cases including a girl imprisoning her stepsister and a serial male killer's murder case. Although her superpower cannot be spoken of to outsiders, relying on the hidden clues revealed by the objects, Huo Ke repeatedly breaks through police investigation deadlocks, cracks major cases, and is ultimately exceptionally recruited into the major crime unit, opening her career path of combating evil.
