Two nations and two species together in the fight against drug traffickers and their unknown accomplices. A story inspired in real events. Violence related to drugs and weapons trafficking has practically created a civil war in Mexico, where executions, shootings, kidnapping, and extortion are daily events. The United States shares the bloody balance with victims of urban violence and deadly overdoses. Characters represent agents and dogs of law enforcement organizations on both sides of the border. Tragedy, deception, greed, and corruption collide against friendship, hard work, family values, and lots of courage.
