Welcome to Baldi's Basics Plus! Your friend, like usual, left his notebooks in the Super Schoolhouse and wants YOU to get them for him! Do you have what it takes to beat Baldi and his friends in five levels of Hide-and-Seek? Collect all the notebooks on all the floors to win!

You enter the elevator and wait to arrive on the first floor, which you eventually do. You press the "start" button and exit the elevator with Baldi greeting you! Baldi: Oh, hi! Let's play Hide-and-Seek! As you walk to the nearest classroom to collect the first notebook from the Math Machine, you can faintly hear Baldi counting down from 10.
