Back to the Future Part III

They've saved the best trip for last... But this time they may have gone too far.

Stranded in 1955, Marty McFly receives written word from his friend, Doctor Emmett Brown, as to where can be found the DeLorean time machine. However, an unfortunate discovery prompts Marty to go to his friend's aid. Using the time machine, Marty travels to the old west where his friend has run afoul of a gang of thugs and has fallen in love with a local schoolteacher. Using the technology from the time, Marty and Emmett devise one last chance to send the two of them back to the future.
