After giving birth, Song Zhenzhen fights postpartum depression with only her dog Doudou by her side. Then the nanny abuses her baby and kills Doudou to make soup. Her husband? Already sleeping with the nanny — the two are after her inheritance and secretly drugging her to lock her in a psych ward. She's seen enough. She installs hidden cameras. Collects evidence. Plays along to dodge the sedatives. Then she strikes — paralyzes her husband, subdues the nanny, and locks them both away. Posing as their psychiatrist, she makes sure every last breath they take is soaked in fear and regret.
