Aleksey Vyazintsev learns that several books by the forgotten Soviet writer Gromov have magical properties. Each of these books gives a specific effect: Rage, Patience, Power, Joy, Strength, Memory. Various groups of readers fight fiercely for them, forming a secret network of Libraries with their own code, rules and goals. Impoverished doctors and engineers, former convicts and cops, forgotten athletes, journalists who did not fit into the tone of the era - they all found a new meaning in Gromov's books and are ready to die for them. Vyazintsev will have to search for the most important book - the book of Meaning.

As an unprecedented wave of book banning is sparked in Texas, Florida, and beyond, librarians under siege join forces as unlikely defenders fighting for intellectual freedom on the front lines of democracy. 　　Kim A. Snyder (Us Kids, 2020 Sundance Film Festival) takes us to an unexpected front line where librarians emerge as first responders in the fight for democracy and free access to information. As they well know, controlling libraries and the flow of ideas means control over communities. 　　Across the U.S., sweeping book bans target stories addressing race and LGBTQ+ issues. Snyder immerses us in this escalating conflict, capturing heated community meetings that lay bare the arguments for censorship. At the center of it all are the steadfast librarians, determined to protect children’s right to access books that educate, empower, and provide solace — despite facing harassment, threats, and even laws aimed at criminalizing their work. A cautionary tale and rallying cry, Snyder captures how these librarians transform their seemingly quiet profession into a bold stand for freedom.
