This short film packs a lot into just a few minutes. Jumper tells the story of an office woman who encounters a suspicious man in the elevator, after which she becomes convinced he's following her and that something bad is going to happen to her. The short story builds suspense effectively and keeps the surprise hidden until the very end. Without giving away any details, the significance of the title becomes clear as the story concludes. Overall, the acting is quite decent, especially given the short runtime and format, and the film is well-made. My only critique is that it might be too realistic-in both good and bad ways.
