HELL ON WHEELSIt' It's a declaration of war against Mexico's biggest drug kingpin, the Morales Cartel. But those out for blood aren't the DEA or Mexican authorities. In a coup fueled by greed, power and betrayal, an unholy Mexican-American alliance is fighting for command of the pipeline on both sides of the border. Using mercenaries as hired guns, the alliance spreads a violence-fueled message: step aside or die. Mack Bolan heads an elite handpicked task force of dedicated soldiers with the skill and grit it takes to infiltrate both ends of the drug-smuggling operation. Guns blazing, Bolan's team rides the road from the Brooklyn-based Winnebago dealership using RVs to smuggle the drugs into the U.S., to the brutal heart of cartel country. But they're up against a trained fighting force paid well to bring back their heads.
