Rio - S1.E4

Though Rio de Janeiro will host the Summer Olympics in 2016, the city currently remains crippled by a war raging between police and powerful drug gangs. Over 2,000 Brazilian military have taken to the streets in a largest offensive in decades. They are taking on the Red Command and Amigos de Amigos, two powerful gangs, in an attempt to regain control of the city's hilltop favelas before the world's eyes focus on Brazil as it hosts the 2014 World Cup and 2016 Summer Olympics. The powerful drug gangs have fought back with a series of urban terror attacks on cars, buses and police stations. Several journalists have been murdered. Photographer Eros Hoagland is one of only a few willing to venture into the dangerous favelas like Mangueira, which overlooks the Olympic stadium. Mysteries are revealed: In some areas of "pacification," Red Command have been warned in advance and have already left for more remote parts.
