The Leprechaun is on the loose again, this time trying his luck in Las Vegas. The terror begins when a young, college student gives a beautiful magician's assistant a lift into town. Once in Vegas, Scott can't resist taking a turn at the roulette wheel. He has a run of bad luck and loses all his money. To win it back he decides to pawn his Rolex watch but while at the pawn shop he finds one of the Leprechaun's gold shillings. A single piece of the Leprechaun's gold, he discovers, will grant the fondest wish of the one who holds it. Thanks to the lucky coin, Scott goes on a winning streak. Unfortunately, the Leprechaun knows his coin is missing and will gladly kill to get it back.
