Molly and her father have inherited a house in Ireland nicknamed "Misfortune Manor"(a house that brings misfortune to all residents). Soon Molly discovers a leprechaun living in the house, and she befriends him. Unfortunately he has no luck because he hasn't eaten a four-leaf clover in over a hundred years. When the bad luck begins to rub off on Molly, she gets into all kinds of trouble. She soon turns things around by growing a four-leaf clover so the leprechaun can use his magic.
