In 1757, in the midst of the French and Indian War, three French divisions and their Huron Indian allies are advancing on Fort William Henry, a British stronghold south of Lake George in the colony of New York. Chingachgook sends his son Uncas, the last living warrior of the Mohican tribe, to warn the fort's commander, Colonel Munro, of the imminent danger. Uncas is admired by Munro's daughter Cora, much to the displeasure of her suitor, Captain Randolph. Upon receiving Munro's plea for assistance, General Webb dispatches a relief force of 3000 men to Fort William Henry with the Munro sisters, but with the aid of an Indian runner named Magua, the sisters and Major Heyward take a shortcut through the wilderness. Magua, who is a Huron sympathizer, then pretends to lose his way. In the forest they encounter Uncas, Chingachgook and the hunter and scout Hawkeye, accompanied by an eccentric preacher named David Gamut. When Heyward asks for directions to Fort Edward, the men become suspicious of Magua who, like all Indians in the area, should have an intimate knowledge of the terrain. Their fears of treachery are confirmed when they discover that Magua has disappeared. Uncas and Hawkeye conceal Heyward and the women in a cave, but Magua and his men find the hiding place, and after a fierce firefight the women are captured. Magua offers to spare "Golden Hair" if Cora will become his squaw; but Uncas, Chingachgook and Hawkeye counterattack and rescue the hostages. Although they leave Magua for dead, he is actually uninjured. The hostages and their rescuers arrive at Fort William Henry at the same time as the column of troops, but the situation is still dire. The only thing keeping the besiegers at bay is a formidable gun emplacement on the left rampart. The cowardly Captain Randolph informs Montcalm, the French commander, that the rampart guns are nonfunctional, leaving Munro no choice but to surrender the fort. Though promised safe passage for the women and children, the Hurons, under the influence of French-supplied whiskey, slaughter the civilians and torch the fort. Magua kidnaps the Munro sisters for a second time and flees. Uncas and Hawkeye pursue him, but Magua reaches a neutral Delaware village. The dispute is taken before a Delaware council of three; their judgment is that Cora be released to Uncas, and that Alice remain with Magua. To save her sister, Cora offers to take her place. Uncas vows that Magua will not leave with his true love; but by Delaware law, Magua is protected until sundown. That night, Cora escapes and is pursued by Magua to the edge of a precipice. She threatens to jump if he approaches, so Magua waits patiently for her to fall asleep. When she does, he grabs her arm. She flings herself off the cliff, but Magua still has hold of her arms. When Uncas appears, the situation is reversed: Cora tries to save herself, but Magua uses his knife to pry her fingers loose, and she falls to her death. In the ensuing fight, Magua stabs Uncas, whose body rolls down the embankment to rest near Cora's. With his final, dying strength, Uncas reaches forth and takes Cora's hand in his. Magua flees when Chingachgook and Hawkeye arrive, but Hawkeye shoots him dead. At Cora and Uncas's burial ceremony, Munro becries the passing of his daughter and Chingachgook mourns for his son, the last of the Mohicans.
