Two women, one born in Canada and the other in Ireland, discover they are half-sisters and embark on a road trip to find their alcoholic father.

Chicagoan Frank Gallagher is the proud single dad of six smart, industrious, independent kids, who without him would be... perhaps better off. When Frank's not at the bar spending what little money they have, he's passed out on the floor. But the kids have found ways to grow up in spite of him. They may not be like any family you know, but they make no apologies for being exactly who they are.

The story of a young group of siblings pretty much abandoned by their parents, surviving by their wits - and humor - on a rough Manchester council estate. Whilst they won't admit it, they need help and find it in Steve, a young middle class lad who falls for Fiona, the oldest sibling, and increasingly finds himself drawn to this unconventional and unique family. Anarchic family life seen through the eyes of an exceptionally bright fifteen year old, who struggles to come of age in the context of his belligerent father, closeted brother, psychotic sister and internet porn star neighbors.
