It is Jay Bartlett's first day as an ambulance driver. Instead of simply delivering his patient to the hospital safely, he hits a pedestrian as they arrive. The victim, Jordan James, is just arriving at the hospital to tend to her husband, who has had a heart attack. Instead of keeping vigil by his side, she is thrown into a coma and her own medical emergency. In his guilt, Jay drops his own life and stays with Jordan. Their lives soon become intertwined both in the present as well as in the past as a story of love over time unfolds.
