It’s a country with the highest homicide rate in the world, where you can literally get away with murder because so few serious crimes are solved. As a result, it's become the main corridor for cocaine coming north from Colombia. That nation is Honduras. Along with its neighbors Guatemala and El Salvador, it's the deadliest region on earth.

CNN’s Kaj Larsen takes you to homicide scenes, meets coffin makers, and embeds with police operations that barely hold the line against the region’s powerful street gangs.

He also introduces you to brave people trying to make a difference, from the outreach workers for Doctors Without Borders – who walk the most violent streets in the world - to the officials fighting the region’s endemic corruption.
