The citizen journalists at Bellingcat.com use open source investigative tools to test the limits of seemingly ironclad international news stories. Who are the white nationalists leading violent attacks in Charlottesville? Was it a Russian missile that took down Malaysia Airlines Flight 17? When and where was a Syrian bombing video actually recorded? These "truth seekers" take high risks from their unimposing living rooms, diving headfirst into mountains of dangerous detail to identify culprits, geolocate atrocities and verify accuracy. Determining fact, fiction or fake news means solving mysteries and exposing myths. Go behind the scenes to witness how this volunteer collective became a thorn in the side of governments the world over. Bellingcat – Truth in a Post-Truth World lifts the veil on journalism, puts the audience in the anchor's chair and gives new meaning to the phrase "breaking news." Nataleah Hunter-Young
