SARA SANDOVAL is the daughter of a rich Mexican banker. MARIA ALVAREZ is the daughter of a poor Mexican farmer. These two women, who seemingly have nothing in common, except their Mexican heritage, end up being thrown together by fate and circumstance, and along with QUENTIN COOKE, a young idealistic New York City Police detective, battle the avaricious land grab by the Texas representative of the New York Bank and Trust, TYLER JACKSON in the year 1880.

At first distrustful of each other, the two women learn through their shared tragedy, (Sara’s father, DON DIEGO, is murdered by Jackson, Maria’s father has his land illegally seized, and is almost killed trying to protect his rights), to cooperate in their battle to defeat Jackson and his band of killers, and return the land he has stolen from the Mexican farmers of their State.

The plan they devise to defeat Jackson is to rob all the banks he has taken over and used to illegally seize the farms of the Mexican peasants. Since neither woman has the skills to successfully carry out their plan they are sent by PADRE PABLO the parish priest, to BILL BUCK, retired curmudgeon of a bank robber, to learn their new found craft.

Armed with their newly acquired skills, the women set out to rob bank after bank, prompting the chairman of the New York Bank and Trust, G.A. ASHE, to send his son-in-law to be, Quentin, down to help Jackson apprehend these Bandidas.

At first convinced of his mission, Quentin sets out to capture the two women and end their careers as Bandidas. However, once they kidnap him, he sees that he has been enlisted on the side of evil, and defects to their cause, using his formidable skills of police science to help them set things right.
