We see a black horse and two men in white dresses. Oh wait, there's a third I didn't recognize before as his dark outfit was almost invisible with him standing in front of the equally dark horse. One of the men in white tries to climb the horse and falls down, and tries to climb it and falls down again etc. This goes on for almost the whole 45 seconds until he finally managed to stay on top of it. Unfortunately, it stopped being funny after the second time already. The black-white contrasts in this one are quite nice and it's good to see them make good use of this feature where all the visuals depended on contrasts with no colors yet available, but that's really all the positive that is to it. Lumière has done much better, also in other films from his very prolific 1895.
