Leprechaun movie plot:
Dan O'Grady goes back to his home in North Dakota in 1983 after visiting his birthplace, Ireland, where he kidnapped a leprechaun and stole his pot of gold. After O'Grady buried the treasure, he found out that the bad leprechaun had followed him home and killed his wife. O'Grady uses a four-leaf clover to stop the leprechaun's magic and put him in a box. He had a stroke before he could set him on fire.
J. D. Redding and his daughter Tory rent the O'Grady home ten years later. Nathan Murphy, Alex, 10, and Ozzie Jones help paint the home. Ozzie misidentifies the leprechaun's screams for help as a child. Using an ancient four-leaf clover, he frees the leprechaun. Ozzie learns from the leprechaun that he's an Irish shoemaker seeking his fortune in America. Ozzie sees a rainbow after failing to convince others he saw a leprechaun, hoping to find a pot of gold. Alex follows Ozzie because he could hurt himself. Before Ozzie, 100 gold coins appear magically. They conceal the riches in an ancient well after Ozzie swallows a coin to mend his brain.
The farm leprechaun fools J. D. by pretending to be a cat and biting his hand. Tory and the others transport the leprechaun to the hospital. Alex and Ozzie visit a pawn shop to inspect the gold's purity. The leprechaun kills the owner, Joe, for stealing his gold and polishes his shoes before departing. On his way home, the leprechaun constructs a go-kart and gets caught for speeding. Leprechaun chases policeman into woods and murders him. The leprechaun returns to the farmhouse and shines every shoe he sees. After dumping off J. D., the group returns to the farm. Nathan is injured by a leprechaun-set bear trap after discovering the house ransacked. The gang beats the leprechaun with rocks and clubs outside.
When they uncover a pistol in the house, they shoot the leprechaun many times. They attempt to leave the property when it doesn't work, but the leprechaun has wrecked the truck's engine. After destroying the truck with the go-kart, the leprechaun terrorizes the group until Ozzie reveals that he and Alex uncovered the pot of money. Tory retrieves the sack from the well and presents it to the leprechaun. They proceed to the hospital, certain that the worst is behind them. As he tallies his treasure, the leprechaun notices that he is missing the final coin that Ozzie ate. He confronts them, certain that they have fooled him, until Ozzie tells them that O'Grady has suffered a stroke and has been admitted to a nursing home. The group diverts the leprechaun's attention by flinging dirty shoes at him, and the leprechaun is forced to shine the shoes while Tory gets into her vehicle and speeds away. Tory travels to the home to learn how to kill the leprechaun.
