Hikaru Shindō is just a normal 12-year-old boy, but one day he's rummaging through his grandfather's things to see if he can find something to sell and pulls out an old go board. A ghostly apparition appears out of the board and tells Hikaru his sad story. His name is Fujiwara no Sai, a man who was a go instructor to the emperor of Japan a thousand years ago. However, because of the bad sportsmanship of his opponent during a game, Sai was accused of cheating and banished from the city. With no livelihood or any other reason to live, Sai committed suicide by drowning himself. Now, he haunts a go board, and wants to accomplish the perfect go game, called the "Hand of God" which he hopes to do through Hikaru. If Hikaru will be able to do it or not (or even wants to) will have to be seen.

Take a nostalgic trip back to the late 1980s through the lives of five families and their five teenage kids living in a small neighbourhood in Seoul.

The drama tells the story of Shi Guang who discovered an ancient go board by coincidence and thus got to know Chu Ying, a go player who has been entrenched in the go board as a "soul" and who has experienced thousands of years. Under his influence, he gradually confronted the story of interest in go and inspiring to become a professional go player.

Since he was a child, the board game baduk has been everything to Jang Geu-rae. But when he fails at achieving his dream of becoming a professional baduk player, Geu-rae must leave his isolated existence and enter the real world armed with nothing but a high school equivalency exam on his resume.
