Tommy and Ethel Barridge, the children of multi-millionaire American business man Henry Barridge, go to Ireland to spend the summer holidays with Laura Duvall, who is engaged to marry their father. However, they find she is a wicked banshee with strong black magic powers who does not wish them well. Laura is busy cutting down trees on her estate and is also planning the destruction of the last king of the little people, or leprechauns. Tommy and Ethel take his side against their wicked future stepmother.
I wasn’t sure where this movie was going at first, but then I quickly caught on. Evil stepmother syndrome, except she’s not stepmother yet, and she’s a banshee living next to a leprechaun’s forest. So it soon becomes an environmental struggle, the leprechaun to save the forest and the banshee to flood it.
Toss in a bit of magic and power, and human enterprise and there is this movie.
In the end the family (plus the housekeeper, who Dad is really in love with before the banshee interfered), must pull together to save each other from the banshee. They even save the leprechaun.
My Rating: ★★★
