Sound Barrier, Penciller for the comic "Hoof of the South Star", is working on the new issue when she finds something weird with the script. Her art directions seem to be inane and written like somepony had never read the actual comic. Looking through it, she finds that they have a guest writer by the name of Grain Miller, a former comic writer who took a turn for the insane. How can she hope to save her comic from this mad writer?
