It is the year 2030. A brilliant robotics engineer creates a robotic boy with robotic powers in the image of his own dead son. The show examines the robotic boy's adventures as he comes to terms with living among humans.
General Jarjayes - so desperate for a son to preserve the family name and noble standing - names his newborn daughter "Oscar" and chooses to raise her as a boy. Fourteen years later, Oscar is a masterful duelist, marksman, and the newly appointed Commander of the French Royal Guards. Her first task: to protect Marie Antoinette, who is engaged to the French prince and future king, Louis-Auguste.
