After returning from a rather paradoxical adventure with Twilight Sparkle, the 11th Doctor begins to question his ability to keep her safe. However, before he can find an answer, he's called back to Equestria. Summoned by the Princesses, The Doctor arrives just in time to witness both past and future events repeat themselves in the present. Faced with a terrifyingly familiar enemy, The Doctor must team up with a few unlikely allies to stop them. But even with their help, will he be able to stop the one pony that hates him the most?
