Ravenous is the 1999 thriller about U.S. army officer who is confronted with cannibalism while stationed at a sierra mountains base in 1846. During the Mexican-American War, U.S. Army Lieutenant John Boyd is exiled to the remote Fort Spencer after his commanding officer finds that he showed cowardice during a battle. Upon arriving at the fort, a stranger by the name of Colqhoun wanders in and explains that his wagon train was stranded in the snow. He also states that a Colonel Ives was responsible for their plight by leading them through a difficult route, and the only way he survived was through cannibalism. Before the party leaves to investigate, the Native American guide warns Boyd of a Wendigo myth where enemies devour human flesh to gain power, but become ravenous demons in the process.
Boyd and his party quickly discover that Colqhoun has led them into a trap. One by one, Colqhoun kills the party members. Boyd escapes but is badly injured. While hiding, he survives off the flesh of one of the murdered soldiers. Once he makes it back to the fort, he tells his unbelievable story to the remaining soldiers who haven't seen Colqhoun. Moments later, Colqhoun shows back up and presents himself as Colonel Ives. Although Boyd warns the soldiers of what happened, the soldiers refuse to believe him.
Colqhoun kills the remaining soldiers and makes a stew with their flesh. With Boyd chained up, Colqhoun admits he attempted the Wendigo myth and was transformed into a cannibal. He also plans to use the fort to trap and kill more victims. Boyd gets loose from the chains and battles Colqhoun. They are both snapped together in a large bear trap. Colqhoun dies first, and Boyd, who could save himself refuses to eat his flesh to live. He too succumbs to his wounds. When General Slauson arrives, he helps himself to a bowl of stew.
