Regal Israeli actress Ayelet Zurer (Angels & Demons) is the best reason to watch this stirring but somber biopic about women’s advocate and political activist Milada Horakova, who survived the Nazi occupation of Czechoslovakia but was executed for treason by the Soviets five years later. Horakova and her courageous husband were imprisoned by the Nazis; their daughter was minded by Horakova’s sister at this time, and also a few years later, when Horakova was arrested and prosecuted by the communists. The girl grew up hardly knowing her mother, which director David Mrnka, a veteran TV news producer, uses as a metaphor for Czechoslovakia’s cultural amnesia (Horakova’s reputation wasn’t restored until 1989, after the Velvet Revolution).
