Biography
The film opens with an archaeologist looking at some artifacts he has dug up from an Indian burial ground. Among these items is the skull of an Indian chief. Suddenly Skeleton Man appears through a portal and kills the archaeologist. Skeleton Man then chases the archaeologist's assistant to a power plant, killing her and the two men working there.

Skeleton Man, now on horseback, kills a soldier and chases his partner. Before being killed, the second soldier manages to record a video and send it back to his bosses. They receive it and send in Delta Force to deal with this unknown threat. As they advance, a female soldier falls behind and is impaled through the chest. The team finds an old Indian man who tells them that Skeleton Man, known as Cottonmouth Joe, was a genocidal warrior who killed the old man's tribe and is now stalking the soldiers. The team pays him no heed.

Meanwhile, Cottonmouth Joe slaughters the workers at an oil pumping station. That night, two sentries are also killed (but are technically MIA as their bodies are never found). The team's scout (Casper Van Dien) also disappears.

The next day, the team encounters Cottonmouth Joe. The heavy weapons specialist charges him but is killed and the team opens fire to no effect. A support helicopter of Citizen's Militia is also destroyed. One man goes to recover the heavy weapons specialist's body but finds it missing. The squad then discovers the team scout, whom they accidentally shot in the firefight (Cottonmouth Joe having captured him and put him in a location to be shot). The team tries to lure their adversary into a trap, but run out of ammo. Another trooper is killed, as is the team sharpshooter who has her skull crushed by a tomahawk.

The two remaining troopers (Captain Leary (Michael Rooker) and Lt. Scott (Sarah Ann Schultz) again try to lure Cottonmouth Joe into a trap to no avail. Skeleton man ends his pursuit of them and heads to a nearby chemical plant where he massacres several workers, two guards, the manager and numerous scientists. The two remaining soldiers arrive and find the place surrounded by law enforcement. Captain Leary takes a sheriff's Armsel Striker and goes to confront the undead adversary. After a cat-and-mouse chase through the chemical plant, Captain Leary lures Cottonmouth Joe into a generator room and blows him up with electric current.

As the film's credits begin to roll, they suddenly reverse and show Skeleton Man back on his horse in the woods, thus indicating that he has survived.
