A madman murders Sir Percival Glyde. Taking on his victim's identity, the man returns to the Glyde ancestral home, Blackwater Park, in hopes of claiming a large inheritance. However, the estate is heavily in debt. Still hungry for wealth, the false "Glyde" takes advantage of a long-standing betrothal promise to marry young and beautiful heiress Laurie Fairlie. Having his true identity revealed could ruin everything, but this lascivious and diabolical "Glyde" is more than willing to kill anyone who stands in his way... This story is loosely based on Wilkie Collins's The Woman in White.
