Mark Genevich is stuck in a rut: his narcolepsy isn't improving, his private-detective business is barely scraping by, and his landlord mother is forcing him to attend group therapy sessions. Desperate for companionship, Mark goes on a two-day bender with a slick and charismatic acquaintance, Gus. When Gus asks Mark to protect a friend who is being stalked, Mark inexplicably finds himself in the middle of a murder investigation.
