Near the end of their collaboration, and still smarting from their famous carpet quarrel, W. S. Gilbert and Sir Arthur Sullivan have neither seen nor spoken with each other in months. Now they must supervise a rehearsal for a revue of their comic operas, a command performance for Queen Victoria. The underprepared show is set to open in about eight hours. Sullivan has been ill and has missed most of the rehearsals; and he’s in love with pretty Violet Russell, a young soprano of whom Gilbert disapproves. To make matters worse, Sullivan has invited Alfred, the Duke of Edinburgh (and son of the Queen), to join the cast. The eager duke can't sing, dance or remember his cues. When Gilbert finds out, he's furious. With a company of temperamental actors to manage, and their producer, Richard D'Oyly Carte, breathing down their necks, there is plenty for the two men to fight about. But their admiration for each other as collaborators and friends wins the day.
