Three American presidents each face a single decision that changes history's direction, and this film picks apart how each choice got made. Lyndon Johnson decides to push the Civil Rights Act of 1964 through Congress despite the political cost to his own party in the South, a calculation that reshapes American politics for a generation. Ronald Reagan commits to the Strategic Defense Initiative, the space-based missile shield nicknamed Star Wars, betting that the Soviet Union cannot match the spending and hastening the end of the Cold War arms race. Franklin Roosevelt, before Pearl Harbor and against strong isolationist sentiment at home, arms Britain through Lend-Lease, a move that keeps the country afloat against Germany and pulls the United States into the war's economics well before its combat. The film treats each case separately, weighing the political risk each president took against what actually followed, from Cold War diplomacy to civil rights law to wartime alliance. The pattern across all three: leaders acting on incomplete information, with consequences neither fully controlled.
