Spike is just an ordinary Canterlot High student who gets a strange sense of deja vu when the new student Trixie Lulamoon transfers in. Matters are only made more confusing when she claims that this is her 13,118th transfer and that she is here to break him. After realizing he is in a time loop, he is forced to work together with her to escape. And at the heart of the plot lies a mysterious entity called Discord and the boxes capable of granting any wish.
