Sam Graves discovers that his elementary school is alive and plotting against the students, and, as hall monitor, it is his job to protect them--but he will need some help from his friends.

Eerie Elementary is planning a big Halloween-type celebration for Eerie Day, including hosting a "haunted house" at the school itself; but the spirit of the evil scientist Orson Eerie sees this as the chance to finally triumph over the intrepid hall moniters, Sam, Lucy, and Antonio--and it is up to them to prevent a catastrophe and perhaps even defeat Orson and banish him from the school forever.

At the end of recess at Eerie Elementary, everything on the school grounds suddenly comes alive and turns into a fog-filled jungle maze intent on trapping and disposing of hall monitor Sam Graves and his friends Antonio and Lucy.

A heavy snowstorm traps the students inside Eerie Elementary, a living, breathing monster brought to life by mad scientist, Orson Eerie--soon the school begins to freeze from the inside out, and Sam, Lucy and Antonio must find a way to get the heat back on before all the students freeze to death, while facing the truth that Orson Eerie is even more powerful and dangerous than they realized.

Sam, Lucy, and Antonio have a new substitute teacher, who happens to be the great-great-grandson of Orson Eerie, the evil scientist whose spirit possesses and infects their elementary school--and the friends are afraid he may be trying to bring Orson back to life.

Only a week into his job as hall monitor and class protector, Sam Graves and his friends Lucy and Antonio are trying to uncover the secrets of Eerie Elementary, their living and malevolent school--and then Lucy gets eaten by her locker.
