Jang Geu Rae has been playing the strategic game "baduk" (similar to chess) since he was a kid. He loved playing the game, but he never achieved the status of professional baduk player. Now he must face the realities of everyday life. He gets a job as an intern at Wonin International thanks to the advice of a friend, but he has a hard time adjusting to life in the corporate world. Ahn Young Yi, a new intern, and Jang Baek Ki, a coworker, are also in the group. Oh Sang Sik is going to be the one in charge.
