David Jackson is living on the edge, partying way too hard and romancing a married woman. Summer has arrived in San Antonio, and now he is headed on a road trip to Mexico with two friends, a high-maintenance redneck nicknamed The Ogre, and a German-American taskmaster named Manfred.

 

David is hoping for a carefree 10 days taking in the sites of Mexico, but secretly harbors a vague hope of a rendez-vous with his lady friend.

 

The further south the boys go, the stranger things get until David begins to wonder whether they will make it back.
