Marge Gunderson, the still pregnant police chief of Brainerd, Minnesota, investigates the murder of a town pharmacist, shot in a snowy parking lot by a stranger who was helping jump his car battery. Meantime, an old man dies of exposure in his ice fishing house, leading one of his sons to kidnap the body. Snow, snow, everywhere.
"In 1997, a pilot was filmed for a television series based on the film. Set in Brainerd, it starred Edie Falco as Marge Gunderson, and was directed by Kathy Bates; the Coen brothers were not involved. The episode was shown during Trio's 2003 Brilliant But Cancelled series of failed TV shows." - Wikipedia
