In the midst of the American Civil War, three ranchers in Texas find their livelihoods destroyed by Confederate raider Luke Cottrell. Kip Davis, Charlie Burns, and Lee Price vow vengeance on their former friend-turned-enemy, leading them down a treacherous path of gun-running and desertion from the Union Army to join the Confederate cause. As allegiances are tested and loyalties are torn apart, the friends must confront the harsh realities of war, betrayal, and the true cost of survival in a nation torn asunder by conflict.
