To be honest, it wasn't as bad as I'd anticipated. Yes, it was extremely low-budget and utterly ridiculous, but I've seen worse. Here's how it all went down:
There's an army guy transporting a barrel of toxic waste through redneck country, and the barrel falls off the truck. A large redneck keeps the barrel and frightens off the army guy. Then the dumb redneck gives the barrel to another redneck family, since he can't read and thinks it will make a good moonshine still. Meanwhile, there's a group of hikers hiking through the woods. Each of them has a distinct personality. There's The Outdoorsman, The Token Black Guy, The Geek, The First Victim, The Token Black Woman, The Surviver, and The Drinking Guy. They all set up camp and get high. At about the same time, the rednecks are sampling their new batch of moonshine, and it's potent. They all start tripping, and the cameraman starts using every built-in camera trick he can find. The next morning, the First Victim goes out to find a place to pee or something, and she's eaten by a redneck zombie. Then Token Black Woman goes out to look for her, and she gets eaten, too. Meanwhile, all the rednecks in town are geting their moonshine delivered.
The rest of the hiking group finds the remains of their companions, and their attacked by a zombie. They kill him with deodorant, but not before he kills the Geek. They take the dead zombie into a cave, and one of the funniest sequences of the movi starts. Basically, the Token Black Guy is on an acid trip and is performing an autopsy on the zombie. It's just weird. Really weird. It's at about this time that we actually start to notice the Drinking Guy. Anyway, they discover that a certain kind of spray-on deodoant will melt the zombies, so they stock up on that (from the Geek's backpack). Now, they wait.
Slowly, the zombies start attacking, and the living start fending them off. Drinking Guy's spray can doesn't work, though, so he chugs some whiskey (or something) and just beats them up. The Outdoorsman gets eaten, and the Token Black Guy pretends to be a zombie. The zombies go after the Drinking Guy. Everyone is upset now, since the Drinking Guy was so cool. He was just pulling liquor out of nowhere and chugging it. It was great. But I digress. The Zombies get the Token Black Guy, and the Survivor runs away. Remember the big redneck from the beginning? Well, he somehow catches and rapes her, and she's saved by the tobacco man. The next thing we see is the Survivor in a mental ward with a glowing womb. She's shaking and in complete shock. Then we see a magazine resting on some guy's foot. It's the Drinking Guy! And he's drinking! Sure, he's missing an arm and a leg, but he's alive!
The drinking guy's cool. He's a lot like Silent Bob. You need to see this movie just for him.
