The Magical Legend Of The Leprechauns

American businessman Jack Woods rents a cottage on the enchanted Emerald Isle which is occupied by a family of leprechauns. Leprechaun Seamus Muldoon's son and son's friends crash the fairies' costume ball and Muldoon's son falls in love with fairy Princess Jessica. Their love re-ignites a feud between the leprechauns and the fairies, which escalates into a war. The Grand Banshee warns of terrible consequences and Jack Woods is chosen to make peace. Woods interrupts his own romance with an Irish beauty to help, and becomes involved in a strange and wonderful magical adventure.

As the war escalates, Mickey and Jessica decide to do something radical: they obtain a poison from the butter-fairies and threaten to take it if their parents won't stop the war. Their parents took them seriously but were unable to make peace, so they take the poison. Their bodies are brought before their parents who immediately become distraught. Jack convinces the warring parties to make peace. Both Muldoon and Boric agree. Kathleen immediately rushes to give an antidote to the lovers but an attack-tunnel dug by general Bulstrode (Frank Finlay) collapses. Kathleen brakes her carriage to avoid the pit. The vial with the antidote flies from her hands and breaks. Jack runs to help and falls into the pit, knocking himself out. Kathleen panics until she learns that he's alright. The Grand Banshee says she can still save them, but only if everyone agrees to peace. Eventually they all do. The Grand Banshee then brings back not only Jessica and Mickey, but all of the lost leprechauns and fairies (with the exception of Count Grogan who the Great Banshee decides to keep so there wouldn't be trouble caused because of him). In the end Mickey and Jessica marry, Jack and Kathleen are reconciled, and the long-lasting war is finally over.
