Brigada Animal - An undercover team in Philadelphia works in the most dangerous areas of the city to combat animal cruelty.
In one covert surveillance operation with the PSPCA undercover team, they make one of the biggest dog fighting busts in Philadelphia's history - 14 suspects are arrested, and several horribly neglected, abused and injured dogs are rescued.
This same team is charged with raiding properties to save as many dogs as possible after the owners are let out on bail. The team finds starved and dehydrated dogs covered in feces, dogs caged in complete darkness and even twelve week old puppies. In total, 41 dogs are rescued from five properties across the city.
After receiving a tip from the narcotics division the team finds a "stash house" - an empty property where illegal dog fights are held. Four of the recovered dogs need emergency care and the veterinarian confirms what officers thought - the dogs' wounds are fresh and the fight could have been as recent as the night before the raid. But with no clues or leads, the team has hit a dead end in the case.
It's not only dog fighting that has infiltrated the seedy underbelly of Philadelphia; the PSPCA is also raging a war against cockfighting. Officers investigate three locations where fighting roosters are believed to be housed. Their cover is almost blown after a drive by surveillance but they return under the cover of darkness. With the evidence in place, SWAT carries out multiple raids, rescues the birds and places their owner in custody.
E.E.U.U. Encubiertos - Journalist Mariana van Zeller and her husband Darren Foster take viewers undercover to see some of the most dangerous and marginalized groups in the U.S.
They investigate how guns fall into the hands of criminals in a dangerous journey that takes them all the way to an underground tunnel in Mexico. Immersing themselves in America's gun culture and with rare access to law enforcement agencies, they expose the legal loopholes and dubious transactions that allow guns to end up on the wrong side of the law.
They also explore the synthetic drug craze in America as they dive deep into this scary world with addicts and health professionals to find out why this bizarre new drug is so appealing to some while considered so dangerous by others. And they will go undercover with Law Enforcement agencies to see if this new breed of narcotics can be shut down by regulation, or if the manufacturers and distributors are already too far ahead of the law.
Mariana and Darren wonder, are extreme animal rights groups eco-terrorists or humanitarians? Undercover investigations by animal activists have produced shocking videos and have led to changes in the food industry, but now these tactics are the target of new legislation that could criminalize such activities. They explore both sides of the debate and go inside the battle between the animal agricultural industry and the animal rights movement.
The husband and wife duo investigate the world of sex trafficking in the United States. Many people think sex trafficking only happens on foreign shores. But here in America, sex slavery is thriving. They gain an insider's perspective from victims and hit the streets with law enforcement and others who are on the front lines, fighting to end this horrific crime.
Traficantes - No one is above suspicion as federal agents at New York's JFK International Airport go on the hunt for Traficantes.
Millions of dollars of contraband are seized annually by agents and officers with the U.S. Department of Homeland Security at New York's John F. Kennedy International Airport, one of the largest hubs for international travel in the United States. It's a job where everything -- from the safety of their team to the security of the nation -- is at stake. Any stone left unturned is an opportunity for criminal activity that could put the country at risk. The only thing they're often given to act on: gut instinct.
Go behind the X-ray scanners and security doors at JFK with officers of U.S. Customs and Border Protection (CBP) and special agents with U.S. Immigration and Customs Enforcement (ICE) in the series Traficantes.
Two major agencies at JFK work together to limit the amount of illegal drugs and banned goods coming into the United States. CBP officers stand at the gates, checking passports and assessing passengers; they are the first line of defense, tasked with observing suspicious activities and making inquiries. ICE's Homeland Security Investigations (HSI) special agents take these cases to the next level to uncover the real source of the criminal activity by exposing contraband and eliciting confessions. Nat Geo Mundo takes you to where cameras are rarely allowed -- into the interrogation room with agents as they identify, search, question and arrest criminals, engaging in a cat-and-mouse game for the truth.
People employ numerous methods to smuggle drugs into the country. Sometimes it's a clever form of concealment; most times, less so. Thorough detective work causes the story of an Ecuadorian man to unravel, and despite continued protestations an X-ray reveals that he's swallowed large pellets of liquid heroin. There's also the story of a random baggage search by CBP officers of an18-year-old reveals cocaine in the lining of his luggage, seeping out through the cracks in his suitcase and mixing in with his clothes. After he's arrested, HSI agents convince him to cooperate and start naming names.
Drugs aren't the only thing these agents are looking for. Fruits, meats and other foreign produce, potentially carrying harmful pests and bacteria that could devastate the country's agricultural industry, are confiscated and destroyed, including nearly 25,000 seizures in 2011 alone. Officers in the mail room inspect nearly 700,000 packages a day for drugs, counterfeit money, exotic animals or worse. For ICE and CBP agents, it's all in day's work.
