The final installment of the Back to the Future trilogy finds Marty (Michael J. Fox) digging the trusty DeLorean out of a mineshaft and looking up Doc (Christopher Lloyd) 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 (Mary Steenburgen), and Marty tangles with Buford Tannen (Thomas F. Wilson).
