Ross Kemp: Extreme World

In the final stage of his latest poke around the inflamed nether regions of the world, our fearless host visits Rio de Janeiro to investigate the drug epidemic that's sweeping through the city. Brazil currently has the seventh-largest economy in the world. A rapidly emerging global power, it's on the verge of hosting this year's World Cup as well as the 2016 Olympics. Yet despite its burgeoning fortunes, it is now the largest consumer of crack cocaine anywhere on the planet. Kemp wades into some of Rio's most lawless districts – known locally as 'cracolandias' - where drug abuse is a 24/7 fact of life and dealers openly carry weapons to combat police raids. He also confronts the harrowing realities of crack addiction, as he meets some of those whose lives have been ruined by this devastating drug.
