John Munin is a rational man, a gifted Montreal psychiatrist who believes that the soul and psyche are interesting only in dissection. His wife, Cynthia, an aspiring artist who paints only self-portraits, remains unconvinced that love can be so quantified. More susceptible to Munin’s searching analysis, though, is Penelope, who suffers from obsessive-compulsive disorder and is Munin’s star patient.
Munin plans to present Penelope’s case at a major medical conference in Nevada. But something has happened to the probing psychiatrist recently, and in the aftermath his orderly world crumbles in the crucible of the desert.
Set against the bizarre backdrop of Las Vegas where fate can change unalterably with the turn of a card, Munin is forced to question all of the truths he has held dear.
