Why is Alex's phone ringing with the My Little Pony theme song that he knows he didn't instaled into his phone? Why is the caller ID showing "Twilight Sparkle; Prime" and "04-12" as a phone number? And why are the "Friendship Problems" he's suddenly encountering sometimes based on episodes of the show he's never seen? Alex's life is a mess. He's isolated, his closest friendships shattered by a misunderstanding. The calls aren't just strange; they're gateways to real-life "Friendship Problems" that mirror episodes of the show – some he remembers, some that are completely unknown. What Alex doesn't realize is that these calls are orchestrated by Twilight Sparkle Prime and alternate versions of herself, who are desperately trying to ensure that he and his friends can stop their world's version of Nightmare Moon and prevent a multiversal paradox that would erase the Equestria Girls timeline.
