January, 1980. At the height of the Cold War, Petra Kelly inspires hundreds of thousands to take to the streets to protest the placement of nuclear missiles on West German soil--including a NATO general named Emil Gerhardt, who shocks the establishment by converting to the cause. Petra and her general not only vault to fame as the stars of the Green Party, but they also fall in love. Then Manfred Schwartz, an ex-lover, urges Petra to draw back the curtain on Emil's war record, and they enter a world both complicated and threatening.
