This episode focuses on couples whose loving relationships are tested by distance and unexpected illness. Forty-year-old Adrian is escalated from majors to Resus after crashing his bike into a car. Adrian recently moved back to London to set up a new life for his family, but at the time of the accident his wife Lili and daughter Luna are 1400 miles away in Montenegro. Consultant Melissa is concerned that Adrian may have a serious chest injury, so he's sent for a full CT scan. As concern grows that Adrian has a collapsed lung and may need emergency surgery, he makes a heartfelt phone call to Lili.
