On a distant planet, a power hungry Leprechaun kidnaps a Dominian princess, Princess Zarina, and plans to make himself king, but not if a bumbling brigade of space marines have anything to say about it. Their commander is a mad scientist by the name of Dr. Mittenhand, who's half machine thanks to one of his "experiments". Once on the planet, Leprechaun is blown up, but quickly is reborn through one of the marines (ala Alien) and wreaks havoc aboard the ship, meanwhile Dr. Mittenhand plans to use the princess for his experiments to make himself whole again. But now, after many of the marines are killed, Leprechaun turns Dr. Mittenhand into a grotesque monster and plans to blow up the ship. The remaining marines have to stop his evil plans and blow *him* up.

It was a normal night in Las Vegas, Nevada, all the lights were flashing brightly, until a man with one hand, one eye, and one leg walks into a pawn shop with a statue of a hideous looking Leprechaun. The owner claims it's a good luck charm. The statue also wore a medallion around it's neck. The careless pawn shop owner took off the medallion setting the Leprechaun free, along with his pot of gold that everyone wants and like before, he'll kill anyone who goes near it. Driving into town that night was a young man named Scott who was off to L.A. to go to school. Along the way he meets a sarcastic, but friendly, girl named Tammy. Scott tries gambling but loses everything, so he goes to the pawn shop to pawn his Rolex watch. At the shop, he finds the dead owner and one of Leprechaun's gold coins that grants a wish to its finder. Scott wishes for a winning streak, but what he does not know is that the casino is run by a crooked man who hates to lose. Also in the casino is an ignorant and dim magician Fazio and Loretta, a middle-aged gal. Before long, Leprechaun shows up to claim his coin, he bites Scott and in the process some of Leprechaun's green blood spills into Scott's wound, so before long Scott transforms into a tall Leprechaun and he needs some help! Only trouble is, the hospital doesn't accept his insurance company: Green Cross. The Leprechaun kills and mauls everyone in his path for his measly gold coin and Scott must choose whether to destroy the pot of gold as well as Leprechaun, or keep it and remain a Leprechaun himself.
