The final girl is a trope in horror films (particularly slasher films). It refers to the last girl(s) or woman alive to confront the killer, ostensibly the one left to tell the story. The final girl has been observed in many films, including The Texas Chain Saw Massacre, Halloween, Alien, Friday the 13th, A Nightmare on Elm Street, Scream and Train to Busan. The term was coined by Carol J. Clover in her book Men, Women, and Chainsaws: Gender in the Modern Horror Film (1992). Clover suggested that in these films, the viewer began by sharing the perspective of the killer, but experienced a shift in identification to the final girl partway through the film.
