本片叙述苏联入侵美国，并屠杀美国的居民，居民都无力反抗，此时有一群年青人联合起来对抗入侵者……From out of the sky, Soviet, Nicaraguan, and Cuban troops begin landing on the football field of a Colorado high school. In a few seconds, the paratroopers have attacked the school and sent a group of teenagers fleeing into the mountains. Armed only with hunting rifles, pistols, and bows and arrows, the teens struggle to survive the bitter winter and the Soviet K.G.B. patrols hunting for them. Eventually, trouble arises when they kill a group of Soviet soldiers on patrol in the highlands. Soon they will wage their own guerrilla warfare against the invading Soviet troops under the banner of "Wolverines!"
