In the isolated fishing community of Aran Island off the coast of Ireland, the always semi-inebriated Garda, Ciarán O'Shea, and his new big-city partner, Lisa Nolan, have their work cut out for them when an extraterrestrial strain of Lovecraftian blood-sucking invaders begin to wreak havoc. But after the chance discovery of the hideous creatures' unexpected aversion to those booze-soaked locals with a high blood-alcohol rate, the entire village will draw themselves into a Bacchanalian lock-in at the local pub, in high hopes of staying alive. However, when is enough alcohol, enough?
