Months after Physical: 100 ushered in a standout year for Korean reality shows, Netflix has premiered its latest cutthroat competition The Devil's Plan. This time, instead of pushing contestants to unthinkable physical feats, 12 super-smart contestants will compete in mind-bending games of wit and strategy with the chance of winning up to 500 million won. As seen in the first four episodes, which were released on September 26, the games will challenge the group in a number of ways, as they navigate who to trust and when to betray their allies. (The first game is basically a supercharged Mafia, for anyone who's familiar with the variety show staple.)

To compete in the games, producer-director Jeong Jong-yeon (The Genius) has gathered an impressive class of super-smart celebrities, YouTube personalities, professional game players, and even a medical doctor. Meet the brainy stars of The Devil's Plan below.
