Set during the Joseon Dynasty, "Chuno" revolves around the world of slave hunters (known as "Chuno Ggun") and slaves (known as "Nobi"). The slaves were sometimes born into the system of servitude and other times became slaves as a punishment for a crime. In the drama series "Chuno," a slave hunter (played by Jang Hyuk) attempts to track down one such runaway slave (playd by Oh Ji-Ho). The runaway slave became a nobi after being falsely accused of a crime he did not commit. While the slave hunter tracks down the runaway slave, he also seeks out the woman he loves (played by Lee Da-Hae).
