In the jungles of Vietnam, innocence is the first casualty of war...

Nineteen-year-old Eddie Henderson is a private in the U.S. Army. His parents are deceased, and he has no one in his life except his platoon brothers—Porter, Rocky, and Professor. His fellow soldiers are his family now. But none share a bond as close as he and his best friend, team leader Mitch Drexler.

In the heat and jungles of Vietnam, each man does the best he can to survive. Battles are fought, friends lost, and promises made to the fallen. But when the enemy fatally wounds a platoon brother in a deadly attack, the dying soldier makes Eddie promise to fulfill a final vow… A debt of blood that could change the course of his life forever.

When Eddie and his friends’ tours are over, they return home to a world they barely remember. But Eddie is still trapped in the past. He has no family, no home to go back to. Just a nightmare he lives over and over again. A dark vow he made to a dying friend. And one question, burning in his mind...

Will he keep his promise to his friend? No matter the cost?
