WEREWOLF

Archaeologists working in the Arizona desert find a skeleton that appears to be a werewolf. The ill-tempered foreman, Yuri, gets into a fight with his crew: Tommy, Joel, and Bill. In the course of the fight, Tommy is scratched by the werewolf skeleton. This greatly alarms his fellow workers, especially Joel, who incredulously utters the word "yetiglanchi". The head archaeologist, Noel, dismisses all Native Americans from the site, but in a private meeting later that day, explains that a major problem may be developing; American Indian mythology holds that a "yetiglanchi" is a dangerous individual who takes on predatory lupine characteristics and kills humans.

Tommy is taken to the hospital, where he begins to exhibit signs of lycanthropy. Yuri sneaks into the hospital and takes a sample of Tommy's infected blood. Shortly thereafter, Tommy fully transforms into a werewolf and escapes after killing several people. Joel and Bill are waiting by Tommy's house armed with silver bullets, and they kill the werewolf in turn.

The action then shifts to a house in suburban Flagstaff, where a writer named Paul Niles arrives to take up residence, having inherited the house from his mother. At a party, Paul is introduced to Natalie Burke, a member of the archeological team present at the time of the original discovery. He takes a romantic interest in her. Yuri is expelled from the party after sexually harassing Natalie, but improvises a plan to create a new werewolf out of an unsuspecting security guard. Yuri drugs the guard before injecting him with a sample of Tommy's blood and is successful in creating another werewolf. This werewolf attempts to drive his car; however, he soon meets his death by running into a stack of flammable oil barrels.

The following day, Paul visits the lab at Natalie's invitation; she has asked him to help publicize their findings and obtain funding for their continued research. However, he is violently attacked by Yuri, who strikes him with the werewolf skull. Paul almost immediately begins showing signs of lycanthropy, even as Natalie attempts to comfort him. An extended series of scenes shows Paul's temperament and physical appearance changing, even as Paul himself remains frightened by the sudden changes. Finally, at a pool hall where Natalie and Yuri are both present, Paul transforms fully into a werewolf, turns feral, and runs out into the streets on a rampage. He assaults several anonymous people and characters from earlier in the film, quickly running away into the woods.

Yuri and Noel speak on the phone about capturing Paul and exhibiting him, but this enrages Natalie, who wishes to save Paul from such a fate. A chase scene ensues in which Yuri attempts to follow Paul into the desert brush, but Paul locates Yuri and violently kills him. Natalie arrives on the scene late, sees Yuri's dead body, and then returns to Paul's apartment. In a twist ending, Paul takes Natalie by the hand romantically, and it is slowly revealed that both of them are now werewolves.

Paul, infected with the curse after being struck by the werewolf skull, transforms fully at a pool hall and runs amok in the streets before escaping into the woods. Plans to capture and exploit him are discussed, but Natalie's outrage leads her to take action against Yuri.

The film ends with the curse still active, as Paul remains at large in his werewolf form. The resolution leaves the threat unresolved, highlighting the dangers of greed and tampering with forces best left buried. Natalie's final actions suggest a shift from exploitation to a more empathetic stance, but the cycle of transformation remains unbroken—fitting for a film where the real monsters are both human and supernatural.
