The roots of Dubcek's lifelong radical leftist beliefs don't lie in Moscow, but in Chicago, where the story begins.
Then we meet young Sasha in the idealistic community of Interhelpo in Bishkek, Kyrgyzstan, which, before its violent "nationalization," founds modern farming in the region. Next, we follow him from establishing the GAZ factory in Nizhny Novgorod, which quickly became the most massive car manufacturer in the Soviet Union until his first meeting with Stalin in Moscow. However, he doesn't accept forced Soviet citizenship and returns to, then pro-Nazi, Slovakia.
We are experiencing the WWII with Sasha in the anti-Nazi guerrilla warfare resulted in the Slovak National Uprising severely suppressed during which Dubček is twice wounded and his brother killed.
Later, already as a member of the Czechoslovak Communist Party Central Committee, Dubček strongly opposites the later agreed draft of the new socialist Constitution. 
Prague Spring of 1968 seems to be a turning point, but Brezhnev, like before Stalin, will betray the idealistic Alexander again and suppress the awakening democracy in Czechoslovakia by military force.
The persecution by the Communist party, paradoxically co-founded by his father, is a sign of another 20 years. After the fall of the Berlin Wall in 1989, the Czechoslovak Velvet Revolution brought him to the top again, but the nostalgic Saša losing his fight with the more progressive Václav Havel.
The controversial car crash in 1992 then ends this saga, which in Dubček's story faithfully reflects the entire communist era of the 20th century in Europe.

Moreover, his wife, and later children, plays a significant part in the story as well as the life-long femme fatale in behinds.
