Now we've lived together in contentment, more or less, for nigh on twenty year. Like turtle doves. - In prison, I mean, for fuck's sake, the chances of that.

PJ and Christy: sworn enemies destined to share one small room for twenty years. As the two men recall the joys and torments of life outside - the childhood excursions, a deadly brawl, past loves and summer dresses - slowly they uncover the tragic events that have lead them to their cell in Montjoy.
