Anime News Network describes the anime as follows:
“Shirobako focuses primarily on Aoi Miyamori, a production assistant at a fictional anime studio called Musashino Animations. The story follows the daily office life and problems that arise in an animation studio, and the workflow in making an anime. Parallel to that, the show also focuses on Miyamori’s friends, who all work or are aiming to work in the anime industry: a key animator, a CG animator, an aspiring voice actress, and a scriptwriter.”
