A hard-drinking policeman and a young, by-the-books detective team up to protect a sleepy Irish fishing village from tentacled alien invaders, and discover an unusual means of making the locals unappetizing in this spirited horror comedy. Erin Island is a tight-knit community where the citizens earn their living from the sea. Located just off Ireland's coast, it's the kind of place where every face is familiar. So when local fishermen begin vanishing without a trace, and whale carcasses begin appearing on the shoreline, boozy cop Ciar?n O'Shea (Richard Coyle) decides it's time to investigate. With the help of Lisa Nolan (Ruth Bradley), a no-nonsense detective from the mainland, O'Shea realizes that something sinister lurks in the area waters, and it seems to be growing stronger. Their suspicions are confirmed when a lobster fisherman returns to shore with a tentacled creature of unknown origins caught in a trap. Upon learning that the predatory extraterrestrials have a particular aversion to alcohol, everyone, including tea-totaling Detective Nolan, attempt to get as hammered as humanly possible while waging war against the strange invaders.
