Escape to Sonoita

Bill and Andy Davis are driving an old tanker truck across the desert when, 85 miles from their destination, they truck develops engine problems. A passing car gets stuck in the sand and it turns out the occupants have kidnapped a young woman in Phoenix and are on the run with the $100,000 ransom they’ve collected. They decide to take the truck to continue their escape but fight over the limited water available. One kidnapper shoots the other, but he eventually dies of thirst. Turns out he was much closer to water than he thought.
