The story of a U.S. Army fire team fractured by racial tensions, moral crises, and the crushing pressures of combat in a war nobody wants to fight. Andre "Casper" Allen, a rough-edged ideologue, finds his radical politics put him at odds with the squad's machine gunner, Silas Meeks. When their search-and-destroy mission in the Mekong Delta goes terribly wrong, both men find themselves pitted against each other and their recalcitrant platoon commander, Lieutenant Sutter.
