When It Will Be Silent is a science fiction short film written and directed by Don Sachar.
You can watch it at the film's site or here:
The Internet Movie Data Base page describes it as "The last day of a love tale in a morbid post apocalyptic world." Twitchfilm says, "it was shot in the no-man's land between Israel and Jordan, and it uses the barren region as an incredibly effective setting". There's a Facebook page. Quiet Earth calls it a "beautifully shot little story".
