Getting to the truth starts with getting to the story. Often that’s easier than said than done.

Many people want to control access and the stakes can be high for those trying to get past them.

Revisiting difficult stories he and other journalists have had to report, BBC International Editor Jeremy Bowen looks at some of the obstacles that stand between journalists and what the Watergate reporter Carl Bernstein called the ‘best obtainable version of the truth’.

Jeremy speaks with: former Reuters journalist Sabina Cosic, Emily Bell - Professor at Columbia University School of Journalism, CNN’s Chief International Correspondent Christiane Amanpour and Eliot Higgins - founder of investigative journalism group Bellingcat.
