Super Junior-M were in Taiwan promoting their new album, Perfection. They added two new members to replace Hankyung, Sungmin and Eunhyuk. One day, they get chased out of town and accidentally enters a forest. They decided to hide there for a while, but when one of them rips open a portal by accident, they all get into a world where the supernatural exists. Once they get in, there's no way out anymore. But was it really an accident? Or will they see their real fate?

And what if the supernatural was actually attractive to them? Who knows what will happen!
