After the Tardis makes an emergency landing on an uncharted planet, The Doctor in an effort to find a way of fixing it comes across a small town filled with multi colored, talking ponies. It's there that he meets a lavender unicorn pony named Twilight Sparkle and her five friends Rarity, Applejack, Rainbow Dash, Pinkie Pie, and Fluttershy. Things seem peaceful at first until the Doctor discovers a plot from an old enemy to not just kill him but enslave the ponies of Equestria as well. It's up to the Doctor and his new friends to stop this from happening.
