After his 13-year-old sister is abducted by sex traffickers, a determined Mexican teen travels from the barrios of Mexico City to a run-down stash house in New Jersey in a desperate attempt to rescue the frightened girl before she is swallowed whole by one of the criminal underworld's darkest secrets. Jorge's (Cesar Ramos) adolescent sister, Adriana (Paulina Gaitan), has been kidnapped and thrust into a lucrative underground trade in which young girls are bought and sold to the highest bidder. Now, as the terrified youngster is herded through a complex network of underground tunnels leading into the United States, her only ally is a Polish woman named Veronica (Alicja Bachleda), who has been tricked into the trade by the same nefarious gang. After circumventing immigration officers and eventually working his way across the border, the desperate Jorge comes into contact with a Texas lawman named Ray (Kevin Kline), whose own devastating personal loss to sex traffickers causes him to join the search for Adriana. In the dark days that follow, Jorge and Ray form a close bond as they witness the horrors of a secret Internet sex slave auction and discover just how far the depths of human depravity can plunge while attempting to maintain hope that brother and sister will one day be reunited. In the world of international sex trafficking, however, innocent victims disappear without a trace every day and few who fall prey to these reprehensible predators are ever seen again.
