Vice has started a new series of illustrated documentary shorts, called Correspondent Confidential:

Journalists go deep. Sometimes they go so deep into a story they lose track of where the story ends and their private life begins. Newspaper reporters, documentary filmmakers, radio producers, and journalists tell personal stories about the harrowing—and hilarious—experiences they've had on the job while reporting on some of the world's most high-profile issues and events.

You can see a trailer for the series here. The first episode was publishes recently: photojournalist Mimi Chakarova talks about her journey deep into the underworld of international sex trafficking. For her film, The Price of Sex, Chakarova posed as a prostitute while working undercover in brothels in Turkey and Dubai:
