Driven by tourism, the last thing the city of Stateline, Nevada wanted to do was announce the presence of a serial killer. Driven by the laws of nature, the last thing Rosa Jimenez wanted was to become his next victim. Called to assist with a gruesome fi nding, Detective Garrett fi nds himself entrenched in an investigation he can't walk away from. Recognizing Rosa from his past, he was resolute that justice be served. As the investigation leads Garrett south, he seeks the assistance of an old friend and current Vice-Detective with the LAPD, David Ross. When Ross is unable to open doors in the Los Angeles area, Garrett realizes his next stop is his hometown on the Mexican border where he stumbles on a link to Los Zetas, a Drug Cartel that has formed an alliance with the Mexican Mafi a. Used to operating with impunity in Mexico, the cartel targets Garrett and his family as his investigation begins to threaten their business. In a daring attempt to make things right, the detectives cross the border to confront the man directing the cartel henchmen.
