Based on the ancient Scottish ballad "Tam Lin" (one of its many titles), the plot concerns an aging, beautiful woman who uses her wealth (and occasionally, witchcraft) to control a decadent pack of attractive young people she surrounds herself with. But when her latest young stud falls for the local vicar's daughter, she vows revenge.
