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 Dooley returns with another hard-hitting series lifting the lid on the global war on drugs.

Along the way she reveals the impact that the west's insatiable desire for more potent drugs is having on the people caught in the crossfire.

Her journey starts in Cambodia, the source of Ecstasy's active ingredient, safrole oil. Here she joins jungle rangers as they patrol the forests to try to stop criminal gangs of loggers chopping down the trees that produce this rare but valuable oil, the raw ingredient of MDMA. From Cambodia, Stacey follows the Ecstasy trail to Vancouver in Canada which is fast becoming one of the biggest centres of production of synthetic drugs on the planet. She joins the police who face a constant battle trying to locate and shut down the clandestine labs turning the oil into Ecstasy pills. Disturbingly, Stacey discovers that as the police get better at intercepting the shipments of oil, the cooks are turning to other chemicals to make Ecstasy, sometimes with devastating effects. Stacey meets the family of one Canadian girl who took a pill she thought was Ecstasy, but which contained a far more powerful chemical - with lethal consequences. Across the world there's an increasing number of Ecstasy-related deaths, linked to unknown and dangerous chemicals being used in its production. In Atlanta in the US, Stacey tracks down drug dealers selling Ecstasy from their 'trap house'. Here it's outstripping meth and crack as the most popular drug they sell, leading Stacey to conclude that what started as a party drug is now well on its way to becoming a street drug, sold by dangerous, warring gangs across the US.

Stacey Dooley travels to Ukraine on Europe's far eastern edge to investigate the struggle to keep drugs out of the UK. Stacey reveals that drug cartels from South America have been using Ukraine as a transit hub to smuggle cocaine into western Europe. To uncover why cocaine shipments are taking this 2,000-mile detour, Stacey visits a new frontline in the war against international drug trafficking - the port of Odessa on Ukraine's Black Sea coast. Ukrainian officials show her the tricks traffickers use to hide drugs within cargoes - inside anything from industrial furnaces to excavated pineapples. But she soon learns from a port worker and a former drug trafficker that Ukrainian customs officials are notoriously open to bribes to get cargoes through. Stacey also discovers that, because the drugs smuggled into Ukraine are too expensive for most local drug users, some are resorting to horrific homemade substitutes. Perhaps the worst is 'crocodile', so called because it rots the flesh of users and turns it scaly. Stacey meets some young addicts as they make a batch from bleach, petrol and tablets bought at the chemist. Learning they have only months to live, Stacey is also shocked to hear that police have recently found 'crocodile' in the UK.
