Horning escapes from the Arizona State Prison and goes on the run, putting his military survival skills to the test. He calls himself a "freedom fighter," and locals call him "Rambo." But to Sheriff Joe Richards, who must hunt him down, Horning is just a dangerous fugitive. Horning goes to the one place he thinks he'll never be found--the Grand Canyon. Living off the land, he evades capture in the longest and largest manhunt in Arizona state history.
