At the brightest moment of the press conference, Su Nian was taken away by the police in public, accused of embezzling 20 million R&D funds. Lin Shen, her fiancé and boss, used forged evidence to turn her into a scapegoat and then left the country with her new love. For 72 hours in the interrogation room, she used professional counter-evidence to open up loopholes, only to discover that this frame-up was vaguely connected to her father's "accidental death" twenty years ago. A stranger wearing a mask delivers anonymous reminders and key clues. Su Nian restarts his life in the abyss: survive first, and then bring everyone back to the judgment seat.
