Using interviews and frontline footage, Vietnam -- The Quiet Mutiny reveals the internal sense of disillusionment and frustration born from the rift between bureaucracy and soldiers, that triggers the withdrawal of the United States military from Vietnam. As the US employs psychological warfare against the Vietnamese, reporter John Pilger finds himself unable to obtain meaningful information from the military—a press conference he attends is nicknamed "the 5 o'clock follies" for the evasive nature of the proceedings. And so it is with the grunts, the "wheels of the green machine," that Pilger finds a very human side to the US presence in Vietnam: soldiers who were once ready to serve their country, now doubtful of their purpose there. Plied with visits from Miss America and ignored by Vice President Spiro Agnew, they experience the war in a way many of their superiors do not.
