Fantasy movie with war for water

An apocalyptic story set in the furthest reaches of our planet, in a stark desert landscape where humanity is broken, and most everyone is crazed fighting for the necessities of life. Within this world exist two rebels on the run who just might be able to restore order.

Catastrophic war, destroyed ecosystem, brink of extinction. War for the most valuable treasure of the time: water.

In a far future, war has destroyed the entire Earth, leaving only a barren wasteland where the supply of water is controlled by a greedy king.

In the not-quite end-times, a woman, a man, a lover and a water smuggler navigate a tumultuous future city on the brink of a water shortage. A "low-fi sci-fi film" secretly made in China.

The tribulations of an engineer and an archaeologist who search for a lost city in the desert of the United Arab Emirates.
