A town—where everyone seems to be named Johnson—stands in the way of the railroad. In order to grab their land, robber baron Hedley Lemar sends his henchmen to make life in the town unbearable. After the sheriff is killed, the town demands a new sheriff from the Governor, so Hedley convinces him to send the town the first black sheriff in the west.
The final installment of the Back to the Future trilogy finds Marty digging the trusty DeLorean out of a mineshaft and looking up Doc in the Wild West of 1885. But when their time machine breaks down, the travelers are stranded in a land of spurs. More problems arise when Doc falls for pretty schoolteacher Clara Clayton, and Marty tangles with Buford Tannen.
