Now separated by political boundaries, the two spend the next three decades trying to reconnect, even as he becomes an astrophysicist and she a member of the fashion industry. They do arrange an encounter in Prague, where Sophie becomes pregnant, but fear of punishment surrounds them, despite their love.
