In the Irish Country town of Kinvarra, the Miller girls are generally perceived to have it all. Single mother and brilliant attorney Stella looks like a Renaissance Madonna and is about to get a second chance at love. TV soap opera writer Tara has just married the love of her life -- the charming Finn -- after a whirlwind six-month romance. And shy, beautiful Holly is living an enviable bohemian life, with artistic friends and a beautiful apartment where her creative talents find an outlet. Have there ever lived three more fabulous sisters? The Miller girls' mother, Rose -- calm, elegant, and unchanging -- is about to celebrate her fortieth wedding anniversary. But as plans for the party of the decade take shape, it's revealed that nothing in the lives of Rose and her daughters is as it seems. And as the secret heartaches the four women have kept hidden from each other begin to emerge, they're set to discover whether they're strong enough to handle the truth -- and whether greater happiness awaits them still.
