Neelamim.

Ne'elamim (The Missing) is a compelling young adult skewed thriller which follows Emma and Alon, a brother and sister who move to a small town and quickly find out that nothing is quite as it seems in their new neighborhood, which is awash with murky happenings. The ground water supply has been geologically poisoned, and three teenagers from their high school died under mysterious circumstances a few months earlier - but when an unexplainable photograph of them surfaces, the siblings begin to doubt that they know the full story, as per the official log-line.
