A battle-weary soldier comes back from the war and goes undercover to avenge the death of his cop brother. His brother's fiancée, who wants vengeance too, tells him his brother had infiltrated a drug-dealing biker gang, the Hellcats, who are employed by the mob to move the drugs from Mexico to the USA. The two would-be avengers infiltrate the Hellcats, the girl is abducted, and now it's the retired soldier against all the bad guys with guns blazing.
