Back to the Future Part III

The last installation of the Back to the Future trilogy finds Marty digging the nimble DeLorean from a mineshaft and searching for Doc at the Wild West of all 1885. Nevertheless, while their time system breaks down, the travellers are stranded at a property of spurs. More difficulties arise if Doc drops for quite schoolteacher Clara Clayton, also Marty tangles together with Buford Tannen.
