Jack Taylor has finally traded in his violent life in Galway for a quiet retirement in the country. But on a day trip back into the city, Jack is hit by a truck and left in a coma, mysteriously without a scratch on him. When he awakens weeks later, he finds Ireland in a frenzy over the so-called 'Miracle of Galway'.

People have become convinced that the two children who tended to him are saintly, and the site of the accident sacred. The Catholic Church isn't so sure, and Jack is commissioned to help find the children - to verify the miracle or expose the stunt. But Jack isn't the only one looking for these children, and he'll need all the help he can get - and a stiff drink of Jameson - once he finds them.
