With the 2014 World Cup about to embark in Brazil and the Olympics around the corner in 2016, the three-part series `Welcome to Rio' takes a timely look at the country's second largest city. The focus is on the notorious favelas, or shanty towns, and the ingenuity of its residents to survive without electricity, sewage or water, and in the midst of drug gangs and violence. As the government attempts to wrest control of the favelas from the gangs - the world needs to see a cleaned-up city, after all - the series shows how those efforts are actually destroying the lives of the people who live there.
