What do you do when your carefully planned life takes a wrong turn into hell?

When Quinn Maguire, a dashing young trauma surgeon, unaccountably accepts a position as an ER physician, her new boss, Honor Blake, suspects that Quinn is hiding a dark secret. While the two declare an uneasy truce in an effort to work together, both struggle with mutual, and unexpected, attraction. Honor, however, has more than one reason to resist her growing feelings for the attractive newcomer - not the least of which is that her heart belongs to the woman whose wedding ring she wears.

Amidst the chaos and drama of a busy emergency room, Quinn and Honor must contend not only with the fragile nature of life, but also with the mysteries of the heart and the irresistible forces of fate.
