The harsh law of the Wild West is not sparing Mexico. Sara, daughter of a wealthy banker, and Maria, from a peasant family, had little chance of sharing the same fate.

Until the day, that is, when Tyler Jackson, representing the New York Bank and Trust, illegally seizes Mexican lands to allow the extension of the American railroad.

Determined to avenge their fathers and protect farmers' land, the two women become bandits, attacking subsidiaries of Bank and Trust. Posted by the NYPD to assist in their arrest, Quentin soon is taken by both females' charm, while Jackson and his men learn to fear the two called the "Bandidas."
