Focusing on "Renxin Hospital", a tertiary hospital, with the emergency department, pediatrics, and intensive care unit (ICU) as the main scenes, it shows the professional dilemma and persistence of doctors on the front line of life and death. The story integrates "medical rescue, doctor-patient conflicts, and career growth", interspersed with plots adapted from real events such as Wenchuan earthquake rescue and the COVID-19 epidemic, highlighting the passion and tenderness of "saving lives and healing the wounded."
