Trashy movie warning! A battle weary soldier comes back from the war and goes undercover to avenge the death of his cop brother. His link to the murder is the fianc'e of his brother, who wants vengeance too, and knows he was an infiltrated cop with a scum drug-dealing biker gang, the Hellcats, who are employed by the mob to move the drugs from Mexico to the USA. 1-star classic 1960's trashiness!
