Mark Allen Johnson puts everything on the line to pursue stories most wouldn't dare. In Discovery Channel's all-new "American Underworld", Johnson enters some of the most extreme, violent and hard-to-access subcultures in the country - from drug manufacturers to the sex trade - to tell the stories of an underground world that could be right next door. Using unorthodox methods, Johnson uses a mix of brains and bravado to gain access to highly secretive worlds. Securing the trust of his subjects alone can be a deadly business, often requiring months of negotiations. Pointing a video camera at them truly puts his life at risk. Entering these worlds - sometimes blindfolded and separated from his crew - Johnson brings back some of the most raw and compelling footage on television.
