The actress, Margot Collins, played Lady Macbeth to great acclaiming her youth. Now in her fifties, she is largely forgotten, struggling for auditions, let alone parts. But when a theatre company announces its intention to stage Macbeth, Margot is determined to land the eponymous role once more - At the auditions it is a younger actress, Chloe, who commands the attention of the director, Richard, but he remembers Margot's inspirational performance and agrees to hear her read. It soon becomes clear, however, that Margot has no chance of starring opposite Brad, a hot TV star, twenty years her junior - and is instead offered the art of one of the witches - But one should never underestimate the spirit of the play to conjure black magic, to summon mishaps and mischief, nor the power of a formidable older woman to get what she wants .
