Charise Castro Smith’s new play packs the action—and rough-justice attitude—of a Tarantino movie into the boudoir of a 16th-century Spanish noblewoman named Maxima Terriblé Segunda. As the nerdy and reclusive sister of dying Queen Isabella, her bedroom becomes a cyclone of machinations over who will take the reins of the brutal kingdom and its slaughtering armies in the New World. “I just can’t believe that I was born at such a relentlessly shitty point in history,” her lover (turned fugitive from the crown) moans, “and there’s nothing I can do about it!” You might sympathize.
