We shadow Sarah Chen, a Level 1 trauma center nurse, through her 12-hour overnight shift in Chicago's busiest emergency department. From managing multiple trauma cases to supporting families during their darkest hours, we witness the unique challenges of emergency medicine after dark. The episode explores how Sarah maintains clinical precision despite her circadian rhythm disruption, her strategies for managing sleep debt, and the profound isolation of missing her children's evening activities. Through her story, we uncover how the hospital's night shift team has developed their own unique support system and rituals to cope with the emotional intensity of overnight emergency care.
