Dermot Coyle enjoys a life of hermetic solitude with just a steady intake of Guinness and a few bets on the horses to pass the time. This all changes when his free-wheeling brother - Ultan - comes back from London. He is to stay just a couple of days, but disappears without trace within hours of arriving in Dublin.
Coyle, reluctantly takes on the task of tracking him down. It leads him to an underworld of smoke and mirrors and forces him to delve deep and find resources of resilience and humanity he had long since buried.
