Major Jim "Lance" Lansing, an American ex-pilot of the U.S. Air Corps, returns to Scotland after the war and finds much trouble in the glen where he settles because of the high-handed activities of the local laird, Sandy Mengues, a wealthy South American who, with his daughter Marissa, has returned to the land of his forefathers. Led by Lansing, the people eventually prevail upon Mengues to restore peace to the glen, but not before a brief and unconvincing fight between Lansing and Dukes, the Mengues foreman.
