Bear falls to earth from an upturned bi-plane, to lock horns with the Deserts of Southern Texas. He's up against some of the harshest terrain in the U.S. Rainy-season storms generate flash floods that shape this landscape into jagged chasms. The rest of the year is brutally hot and finding water is the biggest challenge. As Bear travels through this parched land he traverses deep gorges, locates an oasis in the middle of the desert and takes on a diamond back rattlesnake.
