A patrolman and two innocent bystanders are discovered murdered in cold blood on a snowy highway in North Dakota, leading a very pregnant policewoman, Marge Gunderson (McDormand) on an investigation that uncovers a conspiracy of greed and ineptitude.
Minneapolis husband, father and car salesman, Jerry Lundegaard (Macy), who has long chafed under the thumb of his wealthy boss and father-in-law, concocts an elaborate scheme involving the kidnapping of his wife and a million-dollar ransom to pay off his extensive gambling debts. However, everything that could possibly go wrong does indeed go wrong.
Officer Gunderson's outwardly homespun and folksy persona conceals a penetrating mind and a fierce moral compass, and she easily sees through the poorly executed and badly hidden events perpetrated by the bumbling, yet highly dangerous kidnappers (Buscemi and Stormare).
