I intentionally left this caption a bit vague, but I think the gist of it is pretty clear. There's a competition (called Gemini) that pits couples against one another in various contests over the course of a year. Sounds pretty standard, right? Of course, there's a twist - one of the couple must alter his (or her) appearance in such a way as to become a veritable twin of the other. The contests would be structured to highlight each contestant's struggle with a new gender and identity. Sounds fun, right?
