On their way to the hospital, two girls accidentally discover a mass grave of soldiers who were executed by drug cartel fighters. The bandits try to kidnap the witnesses so that they do not have time to tell the police about what they have seen, but Captain Guerrero of the Special Forces intervenes and gives the attackers a fight back. Having learned about it, the head of the cartel orders to get rid of the SWAT officer and his group. Soon Guerrero and his squad are ambushed and engage in a battle with superior enemy forces.
