Berlin Atomized begins in Buenos Aires of the early 2000s with the self-baptisms of Nina Goldstein. She bathes too frequently, washing with fervor and repeating: "I am not asleep." She grows up partying and taking undeserved siestas, while her eldest brother Jeremías is drawn into the city's powder keg music scene, and the middle sibling, Mateo, learns of his terminal illness and prepares to join the IDF. Though Argentina faces the worst economic crisis in its history, the Goldsteins are being reared in a newly developed gated community that displaces working class families. Each sibling rehearses their escape from the capitalist Eden of their birth, unaware that the gated community will soon be underwater, and their family scattered all over the earth.

The second half of the novel takes place between 2018 and 2035, imagining possible futures for this existence in migration. Jeremías lives in Paris until an undeclared war destroys the city, and Nina, after tracing Mateo's last steps to his death in Tel Aviv, ends up in Berlin, where the European Union is found in the shambles of its own history. The novel progresses into a dire near future of constant flight and fire as the siblings search for one another. Berlin Atomized is Julia Kornberg's napalm-ic debut—a tale about the end of the world, as told by the youth to which that world had been promised.
