Through coincidences of fate and personality, some people seem to do the impossible and make it seem easy. Dan Mesa, former teacher and current Arizona Ranger, is just such a man. He never sought to become a hero; it just happened.

A key member of the Rangers unit in Tucson, Dan is called on to head east, where he picks up William J. Ranson, transporting him to Arizona to testify against Carlos Meana, a trafficker in illegal aliens and murder for hire. Dan's involvement earns him the notice of an eastern crime syndicate who also has ties in Dan's hometown of Tucson. Suddenly, there's a price on his head—but he's not a man to go down without a fight.

Despite dealing with the fallout of killing the man who was once his best friend, Dan will protect the people he cares about, including his son and neighbors at all costs. East meets west as the mob comes to Arizona, and only time will tell which will come out on top.
