Tory sneaks into the rest home in order to talk with Dan O'Grady and find out how to kill the leprechaun, but the leprechaun has gotten there first. Riding in O'Grady's wheelchair, the leprechaun chases Tory down the hall until she jumps into an elevator. Suddenly, O'Grady, with his face all bloodied, falls from the ceiling. As he dies, O'Grady tells Tory that the only way to kill him is to get a 4-leaf clover and place it somewhere on his body. Tory drives back to the house, the leprechaun following in the wheelchair. He catches up with her when she stops to find a 4-leaf clover in the clover patch. He grabs her, and she runs, stopping only when she sees the flashing light of a police car. She jumps into the front seat to find dead Deputy Tripet sitting there. When the leprechaun runs up to the side of the car and tries to grab at her through the window, Tory pokes out one of his eyes with the deputy's nightstick. Suddenly a shot rings out and the leprechaun falls to the ground. Nathan (Ken Olandt) and Ozzie have heard her screams and come running. Together, they comb the clover patch for a 4-leaf clover. Meanwhile, Alex is setting up the bear trap in the barn when the leprechaun jumps him and tries to snap his neck in the trap. Ozzie, Nathan, and Tory enter the barn just in time to save Alex. Ozzie tells the leprechaun that the 100th coin is in his stomach and runs away with the leprechaun in hot pursuit. Alex takes the clover from Tory, wraps it around his wad of chewing gun, and slingshots it right down the leprechaun's throat. The leprechaun begins to disintegrate and falls into the well. As the four of them congratulate each other for killing the leprechaun, he climbs back out of the well, mumbling, "I want me gold." Nathan pushes him back down the well with the butt of his rifle, then pours a can of gasoline around the well. When he ignites it, the well goes up like an atom bomb. As the flames die down, the police finally show up. In the final scene, the leprechaun's voice can be heard coming from the well. "I'll not rest 'til I have me gold. Curse this well that me soul shall dwell 'til I find me magic that breaks the spell."
