Handsome young man Mario Morales (Ricardo Montalban) feels great pressure to become a bullfighter, since his father, Antonio (Fortunio Bonanova), was a famous toreador. However, Mario really aspires to be a composer, and his beautiful sister, Maria (Esther Williams), is the one who wants to enter the bullring. Eventually, the clever Maria disguises herself as Mario to pursue her dream of being a bullfighter, but, despite her talent, the ruse can't last forever. Wikipedia
