Harker Flet and compatriots Timothy X. Nolan and Katy, along with three other men, steal $40,000 in money and jewelry from a California train in the gold-mining country of the 1880’s. The six split up and while they are hiding out awaiting the rendezvous to divide the loot, Hark is cornered, framed and sent to prison. He is released after two-and-a-half years and sets out to find Katy and Nolan and get his share of the loot.

Having fought with the Confederacy during the Civil War, Jesse James and his brother Frank dream of a farm life in Missouri. Harassed by Union sympathizers, they assemble a gang of outlaws, robbing trains and becoming folk heroes in the process. Jesse marries his sweetheart, Zee, and maintains an aura of domesticity, but after a group of lawmen launch an attack on his mother’s house, Jesse plans one more great raid — on a Minnesota bank.
