A magical adventure unfolds when American Jack Woods (Randy Quaid) rents a quaint cottage in Ireland and finds, to his dismay, that the house is inhabited by a family of leprechauns. When one of the little guys (Colm Meaney) and his son crash the fairies' ball, a feud between the leprechauns and the fairies is rekindled. The Grand Banshee (Whoopi Goldberg) warns of terrible consequences, and Jack is chosen to make peace.
