There are three versions to the 1895 documentary, "La Sortie de l'Usine Lumière à Lyon," which has a running time of about one minute: The versions are referred to as, "One Horse," "Two Horses," and "No Horse" - it will be obvious why when you see them.
All three can be viewed right here on Vimeo.
Admittedly not much of a plot.
It is not impossible that, if Jeanne Calment was born on the day this film was released, she still might have been alive this very day (Jeanne Calment remembered meeting Vincent Van Gogh!)
