Plot

The two-dimensional Arthur Square awakens from a dream of strange, glowing symbols. He lives with his wife, Arlene Square, and his curious granddaughter Hex, a hexagon. Hex and Arthur discuss the laws of inheritance: how each new generation of Flatlanders, beginning with triangles, gains a new side until the shapes become indistinguishable from circles. They also discuss how a citizen's shape affects their job, with triangles performing menial labor and circles ruling Flatland in the priest class. They witness a cruel incident where a Circle Priest arrests a slightly irregular octagon child, prompting Hex to yet again wonder what happened to her pentagonal parents. Arthur tells her that he will tell her someday.
