When a former Marine and retired Texas Ranger drops by with evidence indicating terrorists are training south of the U.S. border, Gunner Shake Davis is more than a little interested in the back story. Determined to investigate the situation himself, Shake and his team head south across the Rio Grande where they discover a deadly connection between Middle Eastern terrorists and Mexican drug smugglers.
Following a trail that snakes across Texas leads Shake directly into a deadly confrontation with a truck-bomber at a high-stakes rodeo in Ft. Worth. Shake’s intervention prevents a large-scale massacre, gains him un-wanted nationwide recognition. . . and puts a skilled Zeta assassin smack on his trail. When the situation threatens his family, Shake Davis reverts to close-combat mode to stop the terrorists in a blazing gunfight that echoes across the Texas plains.
