Thirst (2015)

Two friends go on a hike to the desert. In the desolate wilderness something hidden comes out in their friendship. From then on, the only way they manage to communicate is sexually and violently. While one of them wants more than the other is able to give, he expresses his frustration by making sure they get lost and have no water - anything to escape from awaiting reality.

Unfortunately the movie Thirst is not yet available on HBO Max.
