After fixing a strange pipe deep below their city, plumber brothers Mario and Luigi find themselves sucked into a pipe that warps them to a strange new land: the Mushroom Kingdom! As strangers in a strange new place, Mario and Luigi quickly make themselves useful by helping those around town, also aided by the compassionate Princess Peach. However, their meddling with the warp pipe has seemingly caused a chain reaction that leads new dangers to the kingdom- including a monstrous king searching for ultimate power that's become smitten with Peach.
