They're friends for life...and life is for living.

In the picturesque harbour town of Dunmore, four friends are facing hard times. Abby's TV career is taking off, but her marriage to Tom is rocky. Meanwhile, her teenage daughter Jess despairs of ever finding a boyfriend. Lizzie has time for everyone - her family and friends, but never for herself. And Erin, married and back in Ireland after eight years in Chicago, is finding it hard to face up to her past.
