Jealous of best friend Kit, a critically acclaimed but financially unsuccessful author and playwright, Millie writes a novel, the first in a string of bestselling trashy novels. After eight years of neglect and taking a backseat to Millie's fame, her husband Preston leaves her. Another decade passes and Kit announces her intention of marrying the decade-younger Rudd. Millie thinks Preston wishes to reconcile, only to discover he is engaged. He also admits that he was in love with Kit, who had turned down his many advances. Feeling Kit to blame for the failure of her marriage, Millie flies into a rage and confronts Kit. Later, learning of Rudd's affection for Millie's daughter Diedre, Kit graciously steps aside to bless their union. In the end, Millie and Kit make up, sharing a champagne toast for each one's old acquaintance.
