Yeon Jihoon is the leader of the idol group Biggest. Unfortunately, despite their name, they are far from the biggest idol group out there. On the contrary, their most recent album was cancelled, and after a less-than-stellar performance, it looks like the end is near for this short-lived group. That is, until Jihoon gets an opportunity of a lifetime. Due to an unfortunate scandal with another contestant, Jihoon has been asked to fill in on a reality game show with two famous actors. If Jihoon does well, he stands to drag his group up from the dregs of anonymity to superstardom. But Jihoon doesn't realize that these actors he's bunking with aren't as sparkly and clean as their public appearances might be. And, unfortunately for him, they have every intention of dragging him down into their depraved world with them.
