In a customary act of gallantry, Paladin (Richard Boone) acquires opera tickets for Mexican noblewoman Maria Rojas (June Vincent) and her aristocratic husband Miguel (Michael Pate). No sooner have the lights gone down that shot rings out and Miguel is felled by an assassin's bullet. As he lies dying, Miguel persuades Paladin to escort his body back to his home in Mexico. Paladin agrees--little knowing that there is much, much more to this situation than meets the eye!
