Their vehicle crashes through the border fence into Mexico, where Driver is immediately arrested by corrupt Mexican police officers. The crooked cops confiscate the stolen cash, murder his partner, and throw Driver into "El Pueblito," a notorious, lawless Tijuana prison that operates more like a chaotic, self-contained shantytown.
