Guy Noir is a fictional private detective regularly featured on the former public radio show A Prairie Home Companion.
For the portion of A Prairie Home Companion's season that was performed outside of St. Paul, the setting of Noir's case usually involved the city that the program was visiting that week.
Recurring characters in the skits included: Sugar (Sue Scott), a romantic interest; Jimmy (Tim Russell), a bartender; and Wendell (Tom Keith), the boy who worked at the deli around the corner.
In the film, Guy's detective career is faltering, and he works as a security guard at a radio show to pay the bills.
It is strongly implied that he is taken by an angel of death named Asphodel at the end of the movie, played by Virginia Madsen in a trench coat.
Following his untimely 2002 death in a plane crash, the next APHC opened with a Noir segment, skipping even the show's theme song.
