After an argument with Luna, Celestia realizes that she is the only creature in Equestria who cannot sleep in. She enlists Twilight to help, and the two of them come up with a spell that will allow her to spend the night on a different world.

Now, the Princess must decide whether to continue with contact, or destroy the only non-Equestrian witness to their existence.
