The small Irish fishing community of Erin Island comes under attack from a school of blood-sucking aliens, which arrive on Earth on a crash-landed meteorite.
Garda Lisa Nolan (Ruth Bradley) and her booze-sodden sidekick Ciaran O’Shea (Richard Coyle) struggle to fend off the voracious creatures and keep the local residents safe.
Plummy British scientist Dr Smith (Russell Tovey) makes an amazing discovery - the predators can’t tolerate alcohol - which leads to a daring plan of action: get the entire island drunk.
With the help of local landlord Brian Maher (David Pearse) and his wife Una (Bronagh Gallagher), Lisa and Ciaran down shots alongside the rest of the islanders, then attempt to carry out a hare-brained plan while heavily under the influence.
As a storm rages around them, the residents drink the pub dry to survive the night.
