A slightly longer synopsis than the September lineup released by Discovery Family a few days ago has been released for "Viva Las Pegasus". I think the bulk of the episode was already revealed there, but this adds one extra note.
Get it below!
Applejack and Fluttershy follow the map to Las Pegasus where they discover suspicious going-ons at a resort called Gladmane's; they also find Film and Flam working at the resort.
Thanks to Feather Data for sending it.
