Orphaned by a tragic accident at sixteen, Tommy Burwell's been scraping out a meager existence working dead-end jobs for years. When he and fellow nomad Four Trey Whitey get jobs working with dynamite, making way for a new pipeline across the deserted plains of Far West Texas, disaster ensues. In a matter of days, Tommy is brutally beaten and witness to an act of cold-blooded murder the law can't be bothered to investigate.
When Carol, a knockout beauty, shows up looking to follow the caravan of workers, Tommy falls for her almost immediately. There aren't any jobs for women on the pipeline, but Carol knows a few things she could do for the workers to keep afloat — an arrangement that Tommy can't bear for long. As Tommy's about to find out, when you're South of Heaven, you're far from grace - -and sometimes the only way out is down.
