A couple doing drugs in a motel run out of drugs and money. They decide to lure a trucker to their room and then take his drugs or money. Unfortunately for them the trucker who answers is Rusty Nail. He's got plans for them. He chains them to his truck, tapes drugs to his windshield. If they hang on while he drives for a mile, they get the drugs. They survive the mile. But the girl gets to eager for the drugs and reaches for them. That pulls the chain into the truck's U-joint and they yanked under the truck and run over. So far so good.
Next we meet a bunch of rejects from an Asylum casting call for extras. They're supposed to be a racing team. They're on their way to Canada for a race. There's 6 of them, 2 girls and 4 guys, in 2 cars, an SUV with a bed and some little race car. They stop at a diner, discover on a map a shorter route and ask some trucker about the road. It's called slaughter alley because people tend to die there. The crazy trucker warns them to stay away. A cop arrives tells them it's just fine. So they take that road.
The guy who says he's the mechanic is eager to drive the car. When the driver lets him, he becomes aggressive and irresponsible. He cuts a trucker off. Yup, it's Rusty Nail.
Now it's getting dark off course and Rusty has got to take revenge on the kids, kidnapping some and killing those he gets his hands on. Eventually he gets the girlfriend of the driver and tries to exchange her for the car first and then for the guy. The cops get involved as well, but Rusty is always a step ahead.
Joy Ride 3 offers some thrills, some gore, a bit of nudity, some good country music. Leela Savasta is very cute but doesn't get much to do. Kirzinger is a good villain, but unfortunately the dialogue overall is very weak. The least you can do is give your villain some cool lines. This movie tries to be too serious while it lacks the scares or tension or even a strong lead as the kids are entirely disposable. They should have gone for something more tongue-in-cheek given the weaknesses. Like many horror movies this one too, would have been better had they filmed everything during day light. Overall, Joy Ride 3 is a decent sequel, it doesn't stand out, it's not terrible nor particularly good. O'Brien is a better director than he is a writer and producers should keep that in mind and hire a writer for his future projects.
