The document discusses producing an opening film sequence that introduces the overall story. It provides a synopsis of the plot, which involves a couple walking through an idyllic setting that turns sinister, leading the male partner to go missing after being grabbed by an unseen antagonist. The female protagonist then seeks revenge by trying to uncover the backstory of the antagonist and those who originally killed him. Having this synopsis will help the filmmakers design an opening that subtly provides clues about future events and leads smoothly into the full narrative.
