Living in gang-infested Boyle Heights in East L.A., loving family-man Felix Delgado (Leguizamo) does the best he can to provide for his wife, Marina (Perez), and two kids. He reports every day to his blue-collar job as an armored truck driver.

One morning while driving his route, his life is tragically altered when men hijack his truck and force him to participate in a heist of the day’s cash. After murdering his co-workers in cold blood, the thieves shoot Felix in the head and leave him for dead with the incriminating gun placed in his hand.

Felix miraculously survives the close-range blast and, after a struggle on the operating table, regains consciousness with minimal but permanent damage to his brain’s right frontal lobe, but leaving him with a changed personality and paranoid emotions as he remembers the incident.

Felix soon begins to piece together the elements of the crime and descends into the underbelly of East LA to exact revenge on the man he suspects took his life away.
