When the Mane 6 first found out they were being secretly recorded by invisible cameras, they were a little freaked out. After some time, they got used to it. Now, Twilight, Rainbow, Applejack, and Pinkie Pie watch the show regularly. But when Pinkie Pie shows them fimfiction.net, they are greeted by a mysterious message on Pinkie's fimfiction profile. Events are thrown into motion that cause the ponies to explore the darker side of fanfiction, while reading their way through some of the fandom's most infamous grimdark tales. Sort of MST-Style, but in the view of the ponies themselves, rather than the writer of the fic.

Twilight attempts a variation of the teleportation spell in order to teleport long distances. But when the spell goes wrong, Twilight and Rainbow Dash end up swapping places with Mark and Lucas, two humans working on a school project. Both parties struggle to cope with their sudden change in realities, and to deal with the unintended consequences of their actions.
