In the sweltering summer of 1963, at the height of Cold War paranoia, CIA agent Robert "Bob" Maheu is sent to Cuba on a suicide mission: to humiliate Fidel Castro during a live television broadcast by dosing the dictator with LSD and making his beard fall out. But Bob bears the permanent scars of the MKULTRA program, a dark secret in the untold history of the United States' clandestine services. This is the (mostly) true story of how one agency's epic failure set the United States on a collision course with peace, told for the first time as a graphic novel.
