A series of unexpected events lands Dot in hot water and she is plunged back into a life she thought she left behind. Written and directed by Noah Hawley.

In 1950, at the end of two great American migrations - that of Southern Europeans from countries like Italy, who came to the US at the turn of the last century and settled in northern cities like New York, Chicago - and African Americans who left the south in great numbers to escape Jim Crow and moved to those same cities - you saw a collision of outsiders, all fighting for a piece of the American dream. In Kansas City, Missouri, two criminal syndicates have struck an uneasy peace. One Italian, one African American. Together they control an alternate economy - that of exploitation, graft and drugs. This too is the history of America. To cement their peace, the heads of both families have traded their eldest sons.

Season 3 takes place in 2010. A petty sibling rivalry between two brothers escalates and brings chaos to a small Minnesotan community.

In January 2006, Lorne Malvo passes through Bemidji, Minnesota and influences put-upon insurance salesman Lester Nygaard with his malice and violence. Meanwhile, Deputy Molly Solverson and Duluth police officer Gus Grimly team up to solve a series of murders they believe may be linked to Malvo and Nygaard.
