Payload is a very well-executed short science fiction film by Stuart Willis, set in a near-future, dog-eat-dog dystopia a father and his two kids try to scratch a living in the shadow of a space elevator. Willis manages the difficult trick of cramming an interesting and complete narrative into a short timespace while still managing to give us quick character development sufficient to make us care and give us a good feel for this run-down future setting he has placed them in, well worth viewing:
