The theft of the century took place in the historical and archival library. About a hundred rare books and manuscripts disappeared. Journalist Dima Poluyanov, a friend of the “historian” employee Nadya Mitrofanova, came to collect “fried” facts and suggested that the spotter was one of his librarians. Soon, the newspaper's editor-in-chief called Dima and offered him a business trip to America. They say, according to the FSB, the stolen books are in the possession of millionaire Paula Chevy and our professor Vasin is working with them. Pouyanov must interview Paula and find out everything about the books. Poluyanov asks Nadya to keep an eye on the library employees. As a result of this surveillance, she almost died, and when her boss was killed, Nadya, having withdrawn all her savings, flew to America on the wings of fear to meet a real nightmare.
