Twilight Sparkle, impressed with the magical locked compartment that Princess Celestia used to keep the Elements of Harmony, decides to build one herself in the library. Unfortunately, something goes wrong when she is testing it the first time and her horn gets stuck.

Things quickly spiral out of control as her friends try to help. The most well-meaning and innocent intentions...are sometimes easily misunderstood.
