The Texas Chainsaw Massacre: The Beginning
Chrissie and her friends set out on a road trip for a final fling before one is shipped off to Vietnam. Along the way, bikers harass the foursome and cause an accident that throws Chrissie from the vehicle. The lawman who arrives on the scene kills one of the bikers and brings Chrissie's friends to the Hewitt homestead, where young Leatherface is learning the tools of terror.
When danger threatens her camp, the fierce and highly skilled Comanche warrior Naru sets out to protect her people. But the prey she stalks turns out to be a highly evolved alien predator with a technically advanced arsenal.
