 Major Jim "Lance" Lansing (Forrest Tucker), 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 activites of the local laird, Sandy Menzies (Orson Welles), a wealthy South American who, with his daughter Marilla (Margaret Lockwood), has returned to the land of his forefathers. Led by Lansing, the people eventually prevail upon Menzies to restore peace to the glen, but not before a brief and unconvincing fight between Lansing and Dukes, the Menzies foreman.
