The latest season of Doctor Who was very much a mixed bag, but we can all agree that the episode "73 Yards" was one of the finest installments. The episode stepped away from science fiction to tell a chilling British folk horror story.

Set in rural Wales, Ruby Sunday (Millie Gibson) is left alone after the Doctor vanishes. But exactly 73 yards away at all times, a mysterious lady follows her. The distant lady may not be an immediate threat, but she creepily lingers at the same distance. After folk in an inn put fear into her that she's disturbed an old fairy circle, Ruby learns that she must've let loose an ancient curse. Whoever Ruby speaks to about the lady either becomes incredibly hostile or flees in terror.

The episode was a high point for the series. It's currently the highest-rated episode of the new season on IMDb with a rating of 8.2/10. The secrets within its plot remain a mystery; even months after it premiered, fans are still trying to uncover elements of the story...
