Kill the Messenger (2014)

Journalist Gary Webb (Jeremy Renner) happens upon a story that not only leads to the origins of America's crack epidemic but also alleges that the CIA was well-aware of the dealers who were smuggling cocaine into the U.S. and using the profits to arm Nicaraguan rebels. Despite warnings to halt his investigation, Webb keeps digging and uncovers a conspiracy with explosive implications. As a result of his findings, Webb's career, family and life come under threat.
