The power's gone out. To make things worse, all transportation has ground to a halt. Scientists say it's the result of massive solar storms on the surface of the sun. They also say it's permanent. The world has descended into chaos. People are giving up and committing suicide in mass numbers, and there's no indication things will get better anytime soon. In the West Texas city of Lubbock a small contingent of Texas Rangers mounts up on horseback for the first time in over a hundred years. Their main mission is to help the citizens of Lubbock survive the turmoil. With the help of dozens of student volunteers from Texas Tech University, they do their best to make life once again worth living for the survivors. While at the same time dealing with those who'd do them harm. This is a story of how good people deal in the wake of the worst crisis in recorded history. It reflects the best of human nature. And also the worst.
