Mike Waters is a fragile young hustler who lives hand-to-mouth in the city of Portland, Oregon. To compound his vulnerability, Mike suffers from the extraordinary condition of narcolepsy and is prone to swoon into sleep at unfortunate moments. At least he has the support of a street-gang of vagabonds, arrayed around the Falstaffian figure of Bog Pigeon. But in this harsh world, Mike's dearest wish is to find his long-lost mother; and in the course of his pilgrimmage he also hopes for a deeper intimacy with his friend Scott Favor, a wealthy scion who is killing time among the hustlers before taking up his birthright.
