In a time when knowledge is forbidden to women, a brilliant young girl dares to defy the rigid doctrines of the 9th century. Portrayed with fierce intelligence by Johanna Wokalek, Joan disguises herself as a man to pursue an education, a dangerous masquerade that propels her on an astonishing journey from a humble village to the very heart of the Holy Roman Empire. Her path intertwines with a charismatic knight, played by David Wenham, and brings her under the tutelage of powerful figures like the formidable Pope Sergius, brought to life by John Goodman. This sweeping historical drama, directed by Soenke Wortmann, explores the immense personal cost of Joan's secret as she navigates a treacherous world of faith, politics, and forbidden love, constantly balancing her profound intellect with the peril of discovery. The film paints a vivid portrait of a woman challenging destiny itself, weaving a tale of courage and sacrifice against the epic backdrop of a medieval world unprepared for her truth.
