Like many others of his age in Dublin's north inner city, Liam is a small-time criminal whose life consists of dealing drugs, getting into fights and sticking by his friends. But now his girlfriend is pregnant and he wants to change all that to become an electrician and a provider for his new family.
The problem is, his friends: Dots, a crazy thug with ambitions to be a big-time dealer and Scratchcard, a drug user with no ambition but to stay on social welfare and watch the world go by. What's more, Liam's uncle has been murdered, his girlfriend is taking money from a local gangster, and Dots' latest antics are on the point of bringing the roof in on Liam's entire world. Liam has one day in which to make his move from life in the flats to a life on the other side of everything and everyone he's grown up with - but it's St Patrick's Day, and in Dublin that means trouble everywhere.
