Back to the Future Part III – Watch Online Adventure

In November 1955, moments after witnessing Emmett “Doc” Brown disappear in his DeLorean, Marty McFly learns that Doc was sent 70 years in the past to 1885. Using information from Doc’s 1885 letter, Marty and the 1955 Doc find and repair the DeLorean so Marty can return to 1985. However, after finding it, Marty comes across a tombstone with Doc’s name, with the inscription stating that Doc was shot by Biff Tannen’s great-grandfather, Buford “Mad Dog” Tannen, six days after writing the letter.

Marty’s Journey to 1885

Despite the letter’s warning, Marty travels back to 1885 to save Doc, arriving in the middle of a cavalry pursuit of Native Americans, but the car’s fuel line is damaged in the process. Chased by a bear, he is knocked out and found by his Irish-born great-great-grandparents Seamus and Maggie McFly, who allow him to stay for the night. The next morning, under the alias Clint Eastwood, Marty arrives in a newly-founded Hill Valley, but runs afoul of Buford and his gang. Buford tries hanging Marty, but fails when Doc rescues him.

The Showdown and Return

Doc agrees to leave 1885 after learning his fate, but without gasoline, the DeLorean cannot reach its required 88 miles per hour (142 kilometers per hour). He thus proposes using a steam locomotive to push the DeLorean to that speed. While inspecting a rail spur, Doc saves the town’s new schoolteacher Clara Clayton from falling into the ravine, averting her death from the original timeline. They fall in love at first sight and form a close relationship.

At a town festival for the courthouse, Buford tries shooting Doc, but Marty thwarts him. Buford then challenges him to a showdown in two days by calling him “yellow”; an angry Marty accepts, believing that he and Doc would have left by then. Doc urges Marty not to react to provocation, letting slip that Marty has a life changing accident in the future.

A Happy Ending

Although he is reluctant to return to 1985, Doc eventually visits Clara to end their relationship and bid her goodbye. However, feeling insulted, she dismisses his story about being from the future. Despondent, he goes for a binge. In the morning, Buford arrives for Marty, who sees his alias appear in the photograph of the tombstone and refuses to duel. Doc passes out after downing just one shot; he is eventually revived, but is captured by Buford’s gang, forcing Marty into the duel.

On the train to San Francisco, Clara learns how heartbroken Doc is and runs back to town. She finds the model of the time machine at his shop. Realizing that Doc was telling the truth, she heads back to meet him. Using a stolen locomotive named Greyhound, Doc and Marty push the DeLorean along the spur line. Clara boards the locomotive and, attempting to reach Doc, nearly falls off. Marty, in the DeLorean, passes his hoverboard to Doc, and he uses it to save Clara and carry her to safety.

Marty hits 88 mph and vanishes as the overheated Greyhound falls off the unfinished bridge. Arriving back in 1985, Marty escapes from the powerless DeLorean just before an oncoming freight train destroys it. Reuniting with his girlfriend Jennifer Parker, Marty declines a street race with Douglas J. Needles, thus avoiding the future accident Doc warned him about.

The Future Unwritten

As Marty and Jennifer examine the DeLorean wreckage, a steam locomotive suddenly appears, operated by Doc, Clara, and their children. Doc gives Marty a photo of them standing next to the town clock in 1885. When Jennifer asks Doc about the blank fax, he says that it means that their future has not yet been written and encourages them to make it a good one. Doc and his family bid farewell and fly off in the locomotive to an unknown time.
