A pretty young teacher and four of her pretty students take a minibus to some Navajo ruins, little suspecting another kind of ruin awaits. A trio of bikers begin to flirt with the gals, and when their bus breaks down, they helpfully tow the vehicle to a deserted shack. The chief biker, Al, chews up the scenery, kills folks, and rips off the teacher's clothes before raping her. The poor schoolgirls are also in for their share of abuse. 　　译文(2): 一个漂亮的年轻教师和她的四个漂亮的学生乘坐小巴士到一些纳瓦霍废墟，几乎没有怀疑另一种废墟等待。三个骑自行车的人开始和姑娘们调情，当他们的公共汽车抛锚时，他们帮忙把车拖到一个废弃的棚屋。首席摩托车手，艾尔，在强奸老师之前，嚼碎了风景，杀死了人们，撕下了老师的衣服。可怜的女学生们也受到了同样的虐待。
