The curtain goes up on the most famous theatrical family on Broadway: the fabulous Cavendish clan, which has defined unforgettable stage acting for over three generations. While matriarch Fanny Cavendish plans a farewell tour, her leading lady daughter, Julie, has to choose between a dinner date and a first rehearsal — and just when matinee idol brother Tony is on the lam for slugging a Hollywood director. In the meantime, Fanny’s granddaughter, Gwen, is thinking the unthinkable — chucking the whole thing to marry a stockbroker. “Marriage isn’t a career—it’s an incident,” sniffs Fanny. But, the show must go on — and so must the Cavendish tradition: when the curtain falls, the torch is passed from one generation of actors to another.
