Daughter of Don Q (1946) is a Republic Movie serial. It combines elements of the B-Western genre with contemporary crime films, especially the popular "land grab" plot in which the villain attempts to steal apparently worthless land from the heroine (in this case) because he secretly knows it is worth a fortune. In this case, Dolores Quantero, is the rightful heir to extremely valuable metropolitan land which another familt member, Carlos Manning, wants for himself.
