Anna Chen, a divorce mediator and survivor of domestic abuse, runs a modest office with one unwavering rule: her recording pen is never turned off. Having lost custody of her son in her own bitter divorce, Anna dedicates herself to helping women who, like her, once had no voice.
From Megan, a battered wife threatened into silence, to Agnes, who endures forty years of abuse, Anna's pen captures threats, confessions, and the quiet courage of women finally saying "he hit me." The recordings become evidence in court—securing protective orders, child custody, and justice the system alone often fails to deliver.
Facing professional backlash, anonymous threats, and her own unresolved grief over her estranged son, Anna persists. She trains a new generation of mediators, reforms industry practices, and slowly rebuilds her relationship with her son. As she becomes a grandmother, the red light keeps flashing—a steady heartbeat for those still afraid to speak.
