December 1941, Pearl Harbor. A peaceful Sunday morning turns into a devastating attack on American soil. Naval officer Malcolm “Mac” Kelsey is severely wounded while defending his ship. A flawed man abandoned long ago by his alcoholic wife, Kelsey has been mired in despair and hopelessness following the accidental death of Lucy, the young daughter he considers the only redemptive aspect of his life. Near the point of death, Kelsey is brought to what he believes to be an afterlife where he is offered an opportunity to shed his past memories and embark upon an alternate path in another place and time. Eager to escape his torment and begin a more tranquil existence, Kelsey accepts, only to feel quickly betrayed as he soon finds himself back in the midst of battle, this time as a Union soldier at the dawn of the Civil War.
Through Antietam, Gettysburg and four years of relentless fighting, Kelsey attempts to cast aside his painful past while trying to survive the horrors of combat. He crosses paths with compelling figures on both sides of the conflict determined to persevere and return to those they left behind. Idealistic Ethan Royston, promoted from the enlisted ranks, believes in preserving the Union but is plagued by insecurity and self-doubt. His closest friend, West Point-trained Cal Garrity, remains loyal to his home state of Virginia despite his misgivings about the virtue of the Southern cause. The war will divide these friends, just as it will divide Garrity from his adoring wife, Emily, the charismatic and headstrong daughter of a prominent Norfolk shipbuilder, forced to face the onset of war alone.
Each will endure unimaginable hardship and brutality that will forever reshape their core beliefs and values. Each will find their strength and resolve tested as they search for self-purpose, humanity, and reconciliation. Most of all, Mac Kelsey will discover the very essence of life and death, and whether the new beginning he has long coveted will bring him the inner peace he has so desperately sought.
