Based on the book School of Fear by Gitty Daneshavari

Four teenagers-Sweetie Belle, Button Mash, Pipsqueak, and Diamond Tiara-who have serious fears enroll in Celestia's School for Fearful Students, a very secret institution that helps children conquer any irrational or rational fear they may have.

All they have to do is conquer their fears in six weeks or they fail the class. On top of that, they have to deal with Celestia's creepy attorney, Discord, Celestia's obsession with cats, and unorthadox teaching methods.
