This movie contains a portrait of Julia Robinson, a mathematician widely recognized for her contribution to the solution of Hilbert’s tenth problem. Together with her life story, it explains the history and principles of this outstanding result. It is a chronological biography of Julia Robinson recounting her ways and an unquestionable predestination to becoming a mathematician. After explaining her early results, the movie focuses on her main contribution, the work on Hilbert's tenth problem, which gradually gains its own part in the story. The beginning of the film is mainly narrated by her sister Constance Reid (who is a writer and the author of Julia Robinson’s biography) and the rest includes contributions from her colleagues and young professional mathematicians. They explain the basics of Hilbert’s tenth problem and the history of its solution culminating in Robinson’s hypothesis, leaving the final step to a young Russian mathematician Yuri Matiyasevich, who concluded the solution of the problem in 1970. His solution started an unusual friendship between Robinson and Matiyasevich, which overcame both the age gap and political barriers and led to further collaboration. Julia Robinson's results were finally honoured. She was offered a full professorship at Berkeley and was, as the first woman, elected to the American Academy of Arts and Sciences and the presidency of the American Mathematical Society.
