Captain Robert Moray lives in the colony of Virginia during the French and Indian War, and is in love with Alixe Duvarney, the daughter of the Governor of Canada. Moray is captured by the French and taken to Canada where he is held prisoner by Monsieur Doltaire, King Louis' representative in America. Doltaire unsuccessfully tries to compel Moray to reveal the location of some valuable papers, and his hatred for his prisoner increases when he learns about Moray's love for Alixe, whom Doltaire himself admires. Doltaire incriminates Moray as a spy and coerces Alixe to give him up to save his life. They thwart Doltaire, however, when Alixe helps Moray to escape. During the escape, he turns over valuable information to General Wolfe whose English troops storm and capture the city of Quebec, killing Doltaire. Finally, Alixe and Moray are free to establish a new life together.
