High school senior Buffy Summers (Kristy Swanson) is introduced as a stereotypical, shallow cheerleader at Hemery High School in Los Angeles. She is a carefree popular mean girl whose main concerns are shopping and spending time with her rich, snooty friends and her boyfriend, Jeffrey. While at school one day, she is approached by a man who calls himself Merrick (Donald Sutherland). He informs her that she is The Slayer, or Chosen One, destined to kill vampires, and he is a Watcher whose duty it is to guide and train her. She initially rebukes his claims, but is convinced that he is right when he is able to describe a recurring dream of hers in detail. In addition, Buffy is exhibiting uncanny abilities not known to her, including heightened agility, senses, and endurance, yet she repeatedly tries Merrick's patience with her frivolous nature and sharp-tongued remarks.
