Luck can change in the twinkle of an eye.

Nine-year old Molly and her father (Tim Matheson) move to a house they've inherited in Ireland nicknamed "Misfortune Manor." It brings bad luck to anyone who lives in it, and Molly and her father soon fall victim to the curse: they will lose their new house unless they can pay the taxes owned on it.

Then Molly discovers a leprechaun living on the grounds and befriends him. His luck has run out, too, because he hasn't eaten a four-leaf clover in over a hundred years. The bad luck begins to rub off on Molly, getting her into all kinds of trouble. Finally, Molly turns things around by growing a four-leaf clover, and the leprechaun uses his magic to help her win the town's annual go-cart race jackpot to save the day!
