A typical "wrinkle in time" drama from the pen of Richard Matheson, this episode opens as young heiress Anne Henderson (Diana Hyland), taking a horseback ride near her family estate, is suddenly pursued by a witch-like rider dressed in black. This terrifying experience has no effect on Anne's determination to defy her parents' wishes and elope with irresponsible David Mitchell (Robert Hogan). As it turns out, Anne would have been wise to regard the mysterious horsewoman as a portent of disaster. This extremely intense Twilight Zone episode was originally broadcast on February 21, 1964. ~ Hal Erickson, Rovi
