Days before the annual St. Patrick's Day parade, a teenage girl unwittingly unleashes a murderous leprechaun upon the citizens of a small town. The creature goes on a violent rampage, slaughtering descendants of the original settlers who stole its gold. Now the girl and her family have four days to kill the leprechaun – otherwise she will die from the leprechaun curse.
- Alternate synopsis: An evil leprechaun who has been imprisoned within the roots of a majestic old oak tree, is accidentally set loose on St. Patrick's Day. Once free, he takes out his bloody revenge on the descendants of the people who originally imprisoned him.
- Alternate synopsis: Sixty-six years ago, the town of Irish Channel in Louisiana was the site of a horrible massacre on St. Patrick's Day. Some blame a terrible storm that blew through the town, but those that were there don't speak of the truth. Due to petty superstitions, St. Patrick's Day festivities were banned for the last 66 years, but now, the new Mayor wants to tempt fate and celebrate.
- Scripted by Anthony C. Ferrante (Boo, Scream of the Banshee).
- Has also been under the titles Leprechaun's Revenge, St. Patrick's Day Leprechaun and simply Leprechaun, which led to confusion as to whether this was a remake of the original 1993 film.
