One winter morning, in contemporary Dublin, a middle-class woman wakes up next to her husband in her suburban home, and without conscious purpose, walks out the front door to begin a journey that ultimately leads to profound transfiguration. She travels first by car and then train to Rosslare, from where she takes a ferry to Fishguard in Wales. Along the way, she finds herself in service stations, shopping centres, train stations, ferry terminals; recalling her youth, earlier fantasies of suicide and reminiscing about those people who have come in and out of her life. Finally, 48 hours later, alone and isolated in a cottage in Wales, in a strange and eerie landscape, the woman reaches her nadir.
