Nosferatu: A Symphony Of Horror/Nosferatu: Eine Symphonie Des Grauens (1922)

Wisborg, Germany-based estate agent Knock dispatches his associate, Hutter, to Count Orlok's castle in Transylvania as the Count wants to purchase an isolated house in Wisborg. They plan on selling him the one across the way from Hutter's own home. Hutter leaves his innocent wife, Ellen, with some friends while he is away. Hutter's trek is an unusual one, with many locals not wanting to take him near the castle where strange events have been occurring. Once at the castle, Hutter sells the house to Orlok, but he also notices and feels unusual occurrences, primarily feeling like there is a dark shadow hanging over him, even in daytime when Orlok is usually asleep. Hutter eventually sees the Count's sleeping chamber in a crypt, and based on a book he has recently read, believes the Count is really a vampire or Nosferatu. While Hutter is trapped in the castle, the Count, hiding in a shipment of coffins, makes his way to Wisborg, causing death along his way, which most attribute to the plague. Hutter himself tries to rush home to save his town and most importantly save Ellen from Nosferatu's imminent arrival. In Wisborg, Ellen can feel the impending darkness as Nosferatu gets closer. But she learns that a sinless woman can sacrifice herself to kill the vampire.
