Fellow Travelers is the story of the women in the brothers lives: Katya, the peasant girl Victor rescues from the streets of Moscow; Tania, the communist party functionary who eventually becomes his wife; and Yelena, the singer and cabaret entertainer Manny marries and ultimately destroys. Though the story centers on the rivalry between the two brothers, it also reflects the ambitions of their father, a millionaire co-founder of the American Communist Party; his suffragist wife Eva; and Eva's son Eddie, a professional labor organizer and committed defender of workers' rights. Spread across 50 years of history, the scene ranges from the mining camps of Siberia to the opulent mansions of post-revolutionary Moscow, from the political turmoil of New York in the early years of the century to the corporate affluence of postwar America.
