The opening scenes before the title involve women being killed by blades, and then some cross-dressing guy who attacks a woman getting chased and caught. There's a voice-over perhaps relating to that that was cut off on the videotape I watched.
Following that, a couple guys do a robbery, steal a car, sneak up on a couple having sex in a field, kill the guy and rape the woman and steal their car.
Following that, four women go on a geology field trip, and they're unwittingly followed by the two robbers. Predictably, they get stranded and raped, and then fight back. Some Vietnam flashbacks are thrown in to provide some backstory for the two robbers. The ending scenes take place in a police station.
It's not absolutely awful, but it's pretty cheap. Possibly older than 1985, though it references the "Two Wild and Crazy Guys" sketch from Saturday Night Live, whenever that was.
