Batman wakes up in a new world far from his own after stopping Ra's Al Ghul and his League of Assassins from going through with his plan to purge the world.
Now with a powerful artifact in Ra's possession, Batman must make his way through the strange new world without drawing any attention to himself, but that will prove difficult for the Dark Knight in such a world like Equestria.
But the fact that they're in another dimension hasn't stopped the Dark Knight or Ra's. With the assassin allying himself with a powerful threat of this world, can Batman put aside his stubbornness and learn to trust others for help in his battles?
