In 2047 ('twentyfourseven') a new drug, Somnambula, takes away the need for sleep-- no one sleeps, but everyone sleepwalks. On an underground city on the moon, Bruno Flowers, a former circus performer, searches for his missing partner, Falcis, a boy who mysteriously disappeared. The search brings him into contact with Gary Kali, the inventor of Somnambula, who seems to have the power to control others with his mind.
