In a world of fake castles and anthropomorphic rodents, an epic battle begins when an unemployed father's sanity is challenged by a chance encounter with two underage girls on holiday.

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...
