Captain Phillip Kent, a soldier of fortune, and his friend Sergeant Pio, journey from Mexico City to Monterey on a secret mission. Their assignment consists in delivering state-of-the art new guns that will help the Californians fight against Spanish royalists who, disguised as pirates, keep ransacking their towns, villages and forts. Once in Los Angeles, they meet two women, Marguerita and Filomena, who have just missed the stagecoach. Kent reluctantly accepts to escort them but soon falls for the prettier while Pio does not remain insensitive to Filomena. However, after a wonderful night in Santa Barbara, the two ladies vanish in the haze. Overcoming their disappointment, the two men hit the road again and finally reach Monterey where they are welcomed by Lieutenant Ortega, Phillip's best friend.
