Daniel Dillon is an Irish people immigrant who settles in the high mountains of California during the Gold Rush of 1849. It is now 1867, and Dillon has a vault filled with gold and a town of his own, named Kingdom Come. Dillon owns nearly every business of consequence in the town; if someone digs for gold, rents a hotel room, opens a bank account, or commits a crime, they will have to deal with Dillon.
