Shen Qiu, a pediatrician, finds an abortion surgery form in her husband Chen Mo's pocket. The patient turns out to be Zhou Xiaoyu, one of her cancer patients. As she investigates, the mask of the “perfect husband” crashes to the ground: Chen Mo has not only been caring for his gravely ill former love as her “husband,” but has also turned his claws on his own daughter. He switches her medication and fakes an allergy, making four-year-old Duoduo a tool to cover up his affair. When his daughter is on the brink of death from toxic chemotherapy drugs, Shen Qiu is forced to make a choice in just 30 minutes: tear apart the sweet lies hidden beneath her white coat and carve out a way to save her daughter and herself, between the scalpel and the law.
