Thirst(2015)

A couple and their teenage son eke out a living on a hilltop, doing the laundry for local hotels, despite the intermittent water supply. Their simple life is overturned by the arrival of a father-and-daughter team of diviner and well-digger, who promise to bring an end to this precarious existence by finding a source on their arid hill. But ultimately, these newcomers quench a thirst far greater than than the simple need for water.
