Rarity has finally fallen in love with Spike. They want to spend the rest of their lives together. But unfortunately, they can't get legally married, since they aren't the same species. Now they face a legal battle to get the ban on inter-species marriage overturned, as a group of ponies fight to keep the traditional definition of marriage as between a pony and a pony.
