A cop teams up with the former head of a drug cartel to avenge the death of the woman he loved in this action-drama. Sean Vetter (Vin Diesel) and Demetrius Hicks (Larenz Tate) are a pair of DEA agents who think they've made the bust of a lifetime when they capture 'Memo' Lucero (Geno Silva), a multi-millionaire drug lord who controlled most of the narcotics traffic along the border of Mexico and the United States. However, with Lucero behind bars, a new and decidedly more dangerous underworld kingpin rises to take his place, and Diablo (Timothy Olyphant), also known as Hollywood Jack Slayton, soon proves to be even more dangerous than Lucero when he orders his gunmen to assassinate Vetter. While Vetter escapes unharmed, his wife is killed, and Vetter is thrown deep into despair. Now Vetter is obsessed with bringing Diablo to justice, and he's willing to do anything to bring him down -- even if it means teaming up with Lucero.
