Along a long-forgotten Irish road, the O'Reillys live in a rundown trailer stranded in the middle of the fields. Pa, Lisa and their ten children weather the seasons in their tin castle, heirs to a way of life on borrowed time. Under threat of eviction, their tenuous balance falters, yet, steadfast in their tradition, they resist. In a school presentation, Chantelle explains that she has five brothers and five sisters, that she lives in a mobile home because she is an Irish Traveller, and that when she marries, the boy will have to ask her dad first.

Around her, family life carries on at full tilt. Barbie weddings, boxing lessons, communion dresses and a broken generator that leaves them without electricity for a week. When the council offers a house on a crowded estate, with no room for the horses, Pa refuses; he is a Traveller until the day he dies. Alexander Murphy spent six years with the O'Reillys, filming alone until the camera became, in his words, “an eleventh child”. Seen through the children's eyes, it is a warm, unvarnished portrait of a culture slowly fading, and of a tin castle that is, against everything, a home.
