Since she was little, Ha-ram has relied on her sunglasses to keep her sanity, because without them, she begins to see terrible things.

With something to get off their chest Soo-wan and Ha-ram both head to the hospital to see Moo-gang, but he doesn't recognize them at all.

Along with the open-minded Jessan, Hanne gets the gang to agree to a seance. It ends in chaos, Jessan disappears, and for the first time the society is forced down into the dark, menacing basement.

Devastated Ha-ram blames herself for Mu-gang's memory loss. 444 is desperate for Ha-ram's help, but Ha-ram isn't easily persuaded.

Determined to save the boy, Ha-ram heads back to the city of Mujin alone. Black is reminded of his consequences if Ha-ram succeeds in her endeavor.

Waking up from a nightmare about a videotape, Black realizes he's becoming more and more humanized and decides to hasten his search for his partner.

While at the hospital to do a favor for Man-soo, Ha-ram sees a vision of a stranger's death that contains a crucial piece of information.
