1979, London. 19-year-old Tingting Wen's life is not going well. While suffering the effects of a mysterious sleep disorder, she becomes the sole survivor of a massacre where an entire block of market-goers are torn to pieces by an invisible force. She is taken into custody by PARA, an organization that believes her illness is a symptom of a terrible power that has awakened in her. There, she meets Dr. Ruth Morningflower, a rebellious researcher who has plans for Tingting that don't involve keeping her locked in a cell. With the help of Dr. Morningflower and a fellow captive named Terry Lewton, Tingting escapes to hunt down the true culprits.
