Danny Trejo (Machete) packs a punch in this bare-fisted, bone-crunching action thriller inspired by true events. Shunned by society for nearly forty years, Vietnam War veteran Frank Vega (Trejo) becomes an instant celebrity when he thwarts a hate crime on a city bus and footage of the incident goes viral on the Internet. But when his best friend is murdered— and the police seem unwilling to help—Vega takes his new Bad Ass nickname to the extreme against corrupt cops and a crooked mayor (Ron Perlman) in pursuit of oldschool justice!
