Salyut 7

Fall of 1941. Freshly graduated from school, Zoya Kosmodemyanskaya volunteers for a partisan unit. During an assignment, her comrades are ambushed, and she is captured by the Nazis. She endures hours of grueling interrogations and horrendous torture, but defiantly refuses to divulge any information that would compromise other units’ partisan missions. She doesn’t even tell her captors her real name. Zoya’s sacrifice was not in vain; it ignited fire in the hearts of millions of people and became the symbol of selfless heroism during WWII. She is one of the most celebrated heroes of that time.
