30 parts Ongoing Lieutenant Kelly Severide, a fearless firefighter in Chicago's elite Squad 3, faces the daily chaos of life-and-death emergencies. Behind the helmet, though, he is a husband, a protector, and a man carrying the invisible scars of every fire he battles.
Kelly's world is further complicated by his wife, Dr. Alexandra "Alex" Moreno, a dedicated pediatric surgeon whose life revolves around saving the most vulnerable patients. Their professions are worlds apart-one faces destruction and fire, the other, fragile life and illness-but both understand sacrifice, stress, and the weight of responsibility.
When a string of dangerous fires and city-wide emergencies tests Squad 3, Kelly and Alex must navigate the tension between duty and family. Between late-night calls, hospital crises, and the emotional toll of their careers, they struggle to keep their marriage strong while confronting their deepest fears.
Under the Red Helmet is a gripping story of love, courage, and resilience-showing that even heroes need someone to watch their back when the flames die down.
