It's opening night for Long Live Love, a drawing room comedy about a marriage squabble where everything turns out happy in the end. But hours before the curtain is set to go up, George Harold, one of the show’s two playwrights, rushes in with a new, much more cynical version of the script he wrote in an angry, drunken haze.

As the actors scramble to add a tragic ending to their romantic farce, Marjorie Bright, the other playwright—and George’s wife—arrives with a new new ending for the show. Now the actors are stuck in an impossible situation, trying to piece together a working script from the remains of the playwrights’ marriage. Long-lost children, mistaken identities, and sword fights abound in Long Live Love—and that’s just behind the scenes.
