An alcoholic American couple travel to Ireland with their son so he can meet his grandmother but they walk in on their crazed uncle who is in the midst of reviving a centuries-old Druid witch.

After spending time in New York City, Billy Hayes returns to his Ireland hometown. He wants to get back together with his ex-girlfriend and take her to America in hopes of opening up a gas station. But everything isn't going Billy's way — the townspeople aren't happy to see him, and his ex-girlfriend is engaged and pregnant. Then, Billy runs into his old friends who are planning a scam.
