Richard James Aloysius Keane is a lion of the theater, a visionary director, the recipient of a National Medal of Arts for his contributions to American drama . . . and a tired man. His outdoor Elizabethan theatre, the Blue Mountain Rose, lures astute theatergoers from around the world. But after 45 years of service in all weathers, this grand “Wooden O” is showing its age. With the Great Recession of 2009 threatening to consume the endowment, Keane wonders whether it’s time for them both to take a final bow. Kate Moraila isn’t ready to say goodbye yet to this dream of a great theatre in a small town. She hopes their newest actor, Peter Dunmore, will join the fight to save the Rose. But can this “cross between Sir John Gielgud and the young Ken Branagh” attract a new generation of fans to the footlights? Or will his hidden past ring down the final curtain on the fabled Mountain Rose?
