In emergency medicine, the golden hour is the crucial sixty-minute window after a traumatic injury-the brief span of time when the right care can mean the difference between life and death.

Dr. Mason Carpenter lives for that hour.

At St. Mary's Trauma Center, he is the golden boy of the Emergency Department. He's brilliant and calm under pressure. He's also addicted to the adrenaline, the thrill, and the absolute rush of saving patients knocking on death's door.

At home, he's a devoted husband to his high school sweetheart-the love of his life-Honey.

Or, he used to be.

Now Honey is pregnant with their first child.

And Mason is married to his work.

He misses ultrasound appointments, pregnancy milestones, and the baby shower. Worst of all, he is never there to support Honey through an increasingly difficult pregnancy. No matter how many times she tells him she is lonely, exhausted, and afraid, Mason gives her the same answer.

"They need me."

But Honey needs him too.

As her pregnancy progresses and she feels something is deeply wrong, her doctor dismisses her symptoms as first-time-mom jitters. Her husband is too busy saving strangers to see his own wife fading away.

Until Honey collapses at home and is rushed into Mason's emergency room, fighting for both her life and their daughter's.

Mason must reckon with what he was chasing, what he ignored, and what his absence may cost him-the woman he loves more than anything.

Now, the golden hour belongs to Honey.

And Mason may already be too late.
