"Newsflash" is a drama that revolves around Walter Cronkite (Chris Pine), Don Hewitt (Mark Ruffalo), their boss Jim Aubrey, and Dan Rather, a young news man who happened to be in Texas and who first distinguished himself as a dogged reporter as he and other journalists frantically dug for truth after reports went over the wire that gunfire rang out in vicinity of the president's motorcade.

The film takes place on November 22, 1963, the day President John F Kennedy was assassinated in Texas. It was that day that television network news came of age, and Cronkite became the most trusted TV newsman voice of America, even if he wasn't first to announce the president had died (NBC did that).
