In a two-dimensional world called Flatland populated by sapient polygons, it is three days until the celebration of the year 3000. "A Square", attorney at law, struggles to instruct his son, A Hexagon, in the art of sight recognition. The lesson is interrupted by A Square's brother B, a clerk to President Circle, warning A to stay home during a meeting at the Senate of the Great Southern Republic.
The Senate session has been called to discuss the increasing hostilities between the government and the Chromatist movement, led by Senator Chromatistes, which seeks the legalization of Flatlanders coloring themselves as they wish. The Great Southern Republic distinguishes itself from its enemy, the Northern Kingdom, by its stances on Chromatism and Irregulars along with a democratic government. Relaxing the laws has already been perceived as weakness by the Northern Kingdom who are massing on the borders.
Against his brother's warning, A Square meets his new client, the first female charged as a Chromatist. On his way home he is caught in the melee leaving the Senate. President Circle's soldiers killed Senator Chromatistes and his supporters, sparking a riot across the city. A Square just gets home safely, then barricades his family against the chaos for the night.
A Square awakens to learn that the deadly riots originated in the Senate meeting that B Square was attending. He scours the city, now under martial law, seeking B Square. The family prepares for another night, only to be terrified by the sudden appearance of A Sphere, CEO of Messiah, Inc, who has chosen A Square to convince Flatland about the existence of the three-dimensional Spaceland. A Sphere plucks A Square out of Flatland, finally making him understand the third dimension. Having business himself at the Great Hall, A Sphere brings A Square to look for his brother there. On their arrival, A Sphere expounds upon three dimensions to President Circle and the Priests, who anticipated this event. After rejecting A Sphere's message and attempting to kill him, the Flatland leaders execute all who have witnessed the event, except B Square, who is imprisoned for life on pain of death in exchange for his silence.
Realizing that time in Spaceland is short, at least for A Square, A Sphere brings him to Messiah, Inc. to finish his education on the gospel of Three Dimensions. Enthralled by the complex world of Spaceland, A Square posits about the existence of even higher dimension, which A Sphere dismisses. Meanwhile, A Square's intrusion into Spaceland has become a national emergency, which prompts the Spaceland Senate to call to him to appear for a hearing, to explain this breach of protocol of bringing a Flatlander into their midst. They claim that it will be viewed as an act of, and provocation for, war by their enemies, the X-Axis.
A Square learns that the X-Axis wants to destroy Flatland as they consider it an abomination, contrary to the beliefs of the Great Senate. As the debate rages, an ailing A Square tries to explain his theory of multiple dimensions to an unsympathetic crowd. Air-raid sirens wail as A Square collapses from the overwhelming effects of gravity on his two-dimensional body and chaos ensues.
A Sphere manages to send A Square back to Flatland as Messiah, Inc. is bombarded. A Square wakes up on his bed and learns that preaching about a third dimension is illegal now. He finds B Square jailed and explains Spaceland to him, but fearing execution, B Square knocks A Square unconscious. Arriving home, A Square informs his wife that they are going to defect to the Northern Kingdom where he might be able to spread the gospel to a more open-minded populace. Soldiers arrive and A Square escapes with the help of Frau A Square's "war cry" that stuns them. Before he can reach the border, A Square is cornered by the soldiers whose attempt to kill him is thwarted by the Northern Kingdom army's attack. In the fracas, Flatland itself begins to disappear, until a voice welcomes A Square into another dimension.
