THE AMERICAN CIVIL WAR. 1863.

On a cold beach in South Carolina, the soldiers of the 54th Massachusetts Regiment are marching into battle. Their mission: to capture the impregnable Fort Wagner. The odds are heavily against them, and the stakes could not be higher - they are one of the first all-Black regiments in the Union Army, and all of America is watching them.

Among their ranks is William Harvey Carney. A former enslaved man who escaped to the North, he knows what a precious thing freedom is. So when the bugle sounds, and the regimental flag is hoisted high, William charges towards the guns.
