McGregor appears in the teaser as one of two brothers he plays: balding, pot-bellied parole officer Ray Stussy (the other brother is "Parking Lot King" Emmit Stussy). Winstead is his partner in crime, while Coon plays Sheriff Gloria Burgle.
In the promo, Burgle arrives with her son at a diner where Ray and his companion are eating. But when Winstead gives him a significant look, both immediately settle their check and depart, as Coon eyes them with interest.
Not much is known about the plot of the third season, other than its time (2010), brief character descriptions, and the weird/genius idea of casting McGregor as non-twin brothers.
"Fargo" season 3 premieres April 19.
