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.
