Dr. Amal Robardin, a newly-licensed therapist who recently immigrated to Brooklyn from Beirut, is treating her first patient: Yasmin, who is schizophrenic. The two get off to a rocky start, and as Yasmin's night terrors increase and the looming figure at the foot of her bed creeps closer every night, Amal begins to worry that she's out of her depth.
Convinced that what she is experiencing is not a delusion, Yasmin becomes obsessed with Robert Chambers' The King in Yellow. Messages she finds in the book lead Yasmin to flee her home, seeking answers she can't find in therapy.
Distraught over Yasmim's sudden disappearance, Amal attempts to retrace her patient's last steps-and accidentally slips through dimensions, ending up in Carcosa, the King in Yellow's realm. Trapped and determined to find her way out, Amal enlists the help of a mysterious guide, but is he a friend ... or her tormentor?
