This film imitates American westerns and employs Bardot and Moreau, two sexy actresses in French cinema at that time. They play the roles of two quack women, replacing the cowboy roles in American westerns, specializing in fighting against injustice in Latin America. Among them, Maria, the daughter of an Irish politician engaged in an anarchist revolution in Latin America, came across another girl named Maria at the circus after her father was killed. Having forged a deep friendship and witnessed the poverty and rampant violence of the Latin American people, they decided to use their clever talents to assist the revolutionary movement.
