In retaliation for disrupting his operations, Wilkes asphyxiates Dakota in his house and also has Snow killed. Dakota's murder attracts the attention of FBI Special Agent Jackson (Kennedy) who works with Ramos and McQuade. The trail leads them to Wilkes, revealed as an arms merchant who is hijacking U.S. arms shipments for his illicit weapons deals. The three eventually find the arms trading headquarters in the desert. Agents Burnside and Núñez are killed when they attack the headquarters. McQuade and Ramos had tried to stop them, but ended up in the gunfight as well. McQuade is caught and sadistically beaten by Wilkes, who then orders that McQuade be placed in his truck and buried under a truckload of dirt, ignoring Richardson's pleas for mercy for the three men. After regaining consciousness in his truck (a Dodge Ramcharger, 1983 model), McQuade produces a beer and pours it over his face. Then, using his homemade supercharger system, McQuade charges his truck through the dirt – miraculously breaking himself free – and then rescues Ramos and Jackson. All three men are weakened due to being shot and beaten. McQuade finds that Sally has been taken by Wilkes to Mexico. A rival arms dealer known as Falcon, who has been disguising his illegal business as a pinball machine dealer supplies McQuade with this intelligence, claiming Wilkes has double-crossed him and he would like his competition eliminated. Falcon gives McQuade the exact location in Mexico where Wilkes and his daughter are. Though McQuade is intent and tries to head to the location on his own, both Ramos and Jackson have followed him and the three head into the base for the attack. After an intense battle, with Jackson being shot again, and Sally and Richardson escaping, Sally is shot in the leg and both women are sidelined. Finally McQuade and Wilkes engage a hand-to-hand fight with the fight leaning in Wilkes' favor, until he strikes Sally (who ran to her father's aid), provoking McQuade into a frenzy of hits and kicks that defeats Wilkes. McQuade is reunited with his daughter, only to be fired upon by an injured Wilkes. Richardson steps into the line of fire to save McQuade and is fatally wounded. Her dying words to McQuade are that Wilkes killed her husband, forced her to be his arm candy, and that she loved McQuade. Meanwhile, Wilkes and his remaining thug run into a
