Mothers are not supposed to go on road trips...

But one winter morning in Dublin, an ordinary woman wakes up in her ordinary home, her husband next to her in bed, her teenage children sleeping nearby. And - without thinking much about it - walks out the front door and never comes back.

So begins a journey which will take her into service stations and shopping centres, hotel bars and hairdressers - and the beds of strange men.

Until finally, forty-eight hours later, alone in a cottage in Wales, the woman faces up to what she has been ignoring inside herself, her family, modern society: signs of breakdown.
