Two grieving women - Ria, a Dublin mom whose husband discloses he's in love with a woman already pregnant, and Marilyn, a Connecticut Yankee who's son has died - swap houses for a couple months. Marilyn finds solace in Ria's garden and becomes friends with Colm, a local with a restaurant and his own demons. Ria gets a job cooking, has a date or two, and gradually comes out of her shell. Meanwhile, Ria's husband Danny has problems, economic and personal, that may bring more ruin to those close to him. The house on Tara Road comes to stand for the past, for possibilities, and for what can be lost.
