Mankind pillaged Nature until Nature got fed up, and struck back. The 45th Division fights a hopeless rearguard on the Red River, in Oklahoma. Their ranks have been decimated, their equipment is worn out, their morale is shot. The fight is eating them up but they can't retreat, and they sure as hell can't stay here any longer. This is the raw, brutal story of men pushed beyond the limits of human endurance as they fight to stave off final disaster. This is the last day of mankind's last stand against Nature out for revenge.
