Seduced under the arches of Clondarras village bridge, Irish shop girl Rosa Sheridan is persuaded to give up the baby for adoption and make a new life for herself in England. But she can never forget particularly when her happy marriage doesnt bring her the children she longs for. Twenty years later, a successful businesswoman, Rosas life becomes entwined again with three women from her past: the woman who arranged her childs adoption; the woman who adopted her; and Lucy, her child. Together they must work out their destinies in the shadow of the arches.
