Mother 3 is set in a land called the Nowhere Islands. Chaos ensues in the Nowhere Islands after an invasion by the Pig Mask Army, humans in uniforms that resemble pigs. The Pig Mask Army is named for its creator, The "Pig King". The Pig Mask Army slowly constructs a police state, while performing bizarre experiments on the land's flora and fauna. The invaders also introduce new technology and infrastructure to the islands. The story unfolds in different chapters. The various chapters of the story record the trials and tribulations of a boy named Lucas, his family, and friends, who reside in Tazmily Village and band together to rid Nowhere Island of the Pig Army's influence.

Mother 3 starts out very differently from the first two Mother games. The game is set up into eight different chapters, much like Dragon Quest IV. Instead of focusing on a group of children, it chronicles the story and adventures of Lucas and his family, and the story switches perspective during each chapter. (For example, the first half of the game is played as Flint, Duster and Salsa, but the rest of the game is played as Lucas.) Nowhere Island also changes dramatically due to the influence of the Pig Army, transforming from a simple low-tech rural society to a more modern 21st Century infrastructure that's similar to the first two Mother games. (Hence the game's theme of nature vs. technology) The game also features a more traditional top-down RPG perspective, instead of the oblique projection used in the first two games.
