Soon they are in the desert between the border and Joanne s California home. They are intercepted by a gang of American cutthroats sent by Escobar to bring Maria back, as Escobar cannot leave his fight for Mexican freedom.

Along the way, the girls are threatened with torture by knives, rape and attempted rape. Two of the outlaws are killed, Jeff Lawton (David Lloyd) shows up to help the girls and Manuel.

They fight a duel with bullwhips, Escobar proclaims himself the winner and says it isn t fair for Maria to marry him if she doesn t love him, but won t turn her over to Manuel. The gringo outlaws kidnap Maria, and Escobar, Manuel and Lawton pursue them.
