The play, which explores themes of class, power, privilege and the influence of "old money," is set in an elite student dining society at Oxford. In an oak-panelled room, ten young bloods with cut-glass vowels and deep pockets are meeting, intent on restoring their right to rule. The boys bunker down for a wild night of debauchery, decadence and bloody good wine. But this isn't the last huzzah: they’re planning a takeover.
