Stronghold was a compilation of Mexican and US ingenuity. Produced in Mexico using American film stars Veronica Lake and Zachary Scott, Stronghold was distributed in the US by Lippert Pictures. The Juarez revolution against Austrian emperor Maximillian set the scene for this Mexican-American production. Lake portrays a wealthy American visitor who is kidnapped by gentleman bandit Don Pedro Alvarez (Arturo de Cordova) and his gang. Alvarez plans to use the ransom money to help finance the revolution. The heroine manages to orchestrate governmental resistance against the scheme. In the process of time, the honor and patriotism of Alvarez is recognized by Lake's character. Don Miguel Navarro (Zachary Scott), the "heroic" overseer of the silver mine owned by Mary (Lake), is not what he seems to be. See what is brought to light in the film’s spectacular finale.
