Stacey Dooley Investigates: Meth and Madness in Mexico

Stacey Dooley returns with a second series lifting the lid on the global war on drugs. To begin, Stacey is on the trail of the world's most addictive and dangerous drug. Her journey takes her to Mexico, now the world's largest producer of meth, where she discovers that the battle between the cartels, the police and vigilante groups is threatening to overwhelm the very fabric of the state. She joins the army as they track down and destroy the meth super-labs that are now appearing across the country. She tracks down hit men and traffickers who work for the cartels and hears shocking stories of violence from the families of their victims. It becomes clear that the power of the cartels now reaches into every corner of Mexican life and the authorities are increasingly powerless to stop it. Stacey discovers that in some places local people have become so desperate that they are taking the law into their own hands and setting up their own vigilante groups to try and fight off the cartels.
