The game begins with the player mining in a cave when they are greeted by three beings: Action, Knowledge, and Foresight. These beings are called Hosts, caretakers of the Overworld. These three persuade the player to help them save their world, where a war has broken out between the Nether and the Overworld. The player is then transported to that world. After completing a tutorial, the player must save a few villages from being invaded by piglins from the Nether. Then, the player destroys three nether outposts that are preparing to invade villages. Subsequently, the player destroys nine Nether portals from three different world areas. In each of these three areas, the player has to defeat a piglin boss: "the Devourer," "the Beast," and "the Unbreakable". Once the player destroys all of the portals and defeats all of the bosses, the player fights the final boss: "the Great Hog."

Just as the player defeats the Great Hog, it makes a last attempt at destroying the Well of Fate. This backfires and his army is swallowed by a portal that sends them back to the Nether. Then, the Great Hog finally dies. After the battle, there is a grand celebration in the Overworld of their win over the piglins. Not all is well, however. The warrior villagers, who fought alongside the hero, resent the pacifistic villagers who did not, which causes a rift between the two groups. In addition to this, the Hosts have left the world to the Hero's responsibility and moved on.
