In December of 1986, executive sales manager Jerry Lundegaard, who was also Wade's son-in-law, brought Wade and Stan a proposal to buy 40 acres on Wayzata to build a parking lot.
In January 1987, Stan and Wade decide to move forward with Jerry's proposal. When Wade offers Jerry a finder's fee, he becomes enraged, having assumed that they would give him a $750,000 loan to make the deal himself. They decide to cut him out entirely and move on the lot independently.
Later, Stan meets with Jerry and Wade after being informed that Wade's daughter Jean has been kidnapped and is being held for a $1 million ransom. Stan agrees with Jerry that they shouldn't involve the police, and talks his partner out of trying to negotiate the ransom down to half a million.
Stan and Wade go over Jerry's head, however, believing that Wade should deliver the money to the kidnappers personally instead of unreliable Jerry. When Wade does not return from the exchange and Jerry cannot be contacted, Stan begins to get worried. He contacts the police and reveals everything that happened.
Stan learns that Jean was found dead. After Jerry is tracked down an arrested in Bismarck, the fact that Wade was murdered and that Jerry orchestrated the entire kidnapping is also revealed. Afterwards, Stan is left in control of Gustafson Motors.
In the decades after the tragedy, Stan Grossman gets into the real estate business, buying plots of land as Jerry Lundegaard once tried to do. Instead of building lots, he builds condominiums, and has become fairly wealthy by 2010. He is also acquainted with Emmit Stussy, the "Parking Lot King of Minnesota."
