Importance of Being Earnest

Algernon is a gentlemen from a wealthy family. Algernon's close friend Jack, has a ward, Cecily. Both Algernon and Jack have created alter egos to make life more interesting. Algernon arrives for a weekend visit in the country posing as Earnest. Having heard of Earnest's misadventures, Cicely has developed an infatuation with the rogue, and Algernon's impersonation of him works famously on Cicely. Meanwhile, Algernon's cousin, Gwendolyn, arrives for the weekend, and is startled to discover Jack is also there -- except that she knows him as bad-boy Earnest. So just who really is who?
