| In 1955, Marty McFly and Doc Brown use the information in Doc's 1885 letter to retrieve and repair the damaged DeLorean (which has been waiting for him in a mineshaft for 70 years). As they retrieve the car, Marty spies a tombstone with Doc's name, dated six days after the letter. Learning Doc was killed by Biff Tannen's ancestor, Buford "Mad Dog" Tannen, Marty decides to go back to 1885 to save Doc and bring him back to the future. |
在1955年，馬蒂?麥克弗萊和布朗博士按照博士于1885年寄出的信里的說明，找回并修好了損壞的德羅寧時光機（這輛跑車已在礦井里保存了70年）。在他們找回跑車的過程中，馬蒂發現了一塊墓碑，上面刻有博士的名字，死亡時間就在信寄出后的第七天。馬蒂調查出博士是被畢夫?泰南的祖先——綽號“瘋狗”的布福德?泰南殺害的，于是他決定回到1885年去救出博士，再一起回到未來。 |
| Marty arrives on September 2, 1885, in the middle of a United States Cavalry pursuit of Indians. Unfortunately, an arrow has ripped a hole in the fuel line, emptying the gas tank and rendering the DeLorean engine useless. Furthermore, Doc falls in love with the local schoolteacher, Clara Clayton, and considers staying in 1885. Marty must convince Doc to come back with him and find a way to get back to his time before it's too late. |
馬蒂乘時光機來到1885年9月2日，正好出現在美國騎兵追逐印第安人的戰場上。不幸的是，一支箭在德羅寧的燃油管上扎了一個洞，跑車漏光了油，因此無法再啟動了。更糟的是，博士愛上了當地的女教師克拉拉?克萊頓，打算就此留在1885年。馬蒂必須在謀殺發生之前勸服博士和他一起回去，還要找出辦法回到他原本所在的時空，否則一切就太晚了。 |
| Buford tries killing Doc at a town festival but Marty intervenes; Buford then goads Marty into a showdown in two days' time. Doc reluctantly decides to return to the present with Marty. With the fuel tank in the DeLorean empty and gasoline unavailable, he devises a scheme to use a locomotive to push the DeLorean up to speed. |
布福德試圖在小鎮的慶典上殺死博士，但是馬蒂阻止了他。布福德于是用話激怒馬蒂，逼他答應兩天后與自己決斗。博士不情愿地決定和馬蒂一起回到他們的時空。因為德羅寧的油箱已空空如也，在1885年也不可能找到汽油，所以他計劃用火車頭推動德羅寧時光機以達到穿越時空所需要的速度。 |
| The night before their departure, Doc, despondent about his lost love, returns to the town saloon to get drunk. Marty rides to the saloon and convinces Doc to leave with him, when Buford arrives and demands the duel to take place immediately. Marty realizes his reputation is unimportant and refuses to fight. But Buford's gang captures Doc. Marty uses a steel door to a furnace as a bullet-proof shield, and knocks Buford out. With Buford no longer a threat, Marty and Doc steal the locomotive. |
他們出發前的晚上，博士因為他失去的愛情而悶悶不樂，回到鎮上的酒館買醉。馬蒂騎馬趕到酒館，勸說博士和他一起離開。就在這時，布福德忽然現身，要求立刻與馬蒂決斗。馬蒂意識到他個人的名譽并不重要，毅然棄權。然而，布福德一伙抓住了博士。馬蒂用一塊鐵制的爐門擋住了布福德的子彈，并將他擊昏在地。不用再顧忌布福德構成的威脅，馬蒂和博士成功地偷到了計劃所需要的火車頭。 |
| Meanwhile, Clara discovers Doc's model of the time travel experiment and rides after him. She boards the speeding locomotive and climb out to Doc while he is climbing towards the DeLorean. Unfortunately she falls off the side, hanging by her dress. Doc uses Marty's hoverboard to save Clara. They coast away from the train safely as the DeLorean disappears through time with Marty. |
與此同時，克拉拉發現了博士制作的時空旅行實驗的模型，于是騎馬去找自己的愛人。當博士從火車頭爬向德羅寧跑車的時候，克拉拉也登上了高速行駛的火車，鉆出車窗向博士爬去，結果不幸從側面掉了下來，整個人被裙子掛在了車頭上。博士踩著馬蒂的飛行滑板救下了克拉拉，兩人離開火車，滑行到了安全的地方；而馬蒂則與德羅寧跑車一起消失在時空隧道中。 |
| Marty arrives safely on October 27, 1985, but the powerless DeLorean is destroyed when a freight train strikes it head-on. Marty returns to his home, discovering that everything has returned to the improved timeline. Marty finds Jennifer sleeping on her front porch. Later, Marty uses the lessons he learned in 1885 to avoid being goaded into a street race, avoiding the potential automobile accident which would cause more downward turns for the McFly family in the future. |
馬蒂安全地回到了1985年10月27日，然而那輛失去動力的德羅寧跑車被一列貨車迎頭撞上，零件四散。馬蒂回到家里，發現一切都回到了他最初改善過的樣子，女友詹妮弗也依舊在自家的門廊上熟睡。之后，馬蒂吸取他在1885年得到的教訓，不再因為被人激將而參加公路飆車，因而避免了原本會發生的車禍，由此改變了未來麥克弗萊一家逐漸沒落的命運。 |
| Marty takes Jennifer to the time machine wreckage. They worries that Doc has been lost in the past forever, when suddenly Doc Brown appears in a new time machine modeled after a locomotive with Clara (to whom he is now married) and their two sons. Doc tells Marty and Jennifer that the future has not been written yet, and that it is "whatever you make it, so make it a good one." After the Browns bid farewell to their friends, Doc's train converts into a hovertrain and roars off into an unknown time. |
馬蒂帶著詹妮弗來到散落著時光機殘骸的地方。他們擔心博士將會永遠地留在過去的時空中。就在這時，布朗博士忽然駕駛著新的時光機出現了。這部機器的外形是一個火車頭，上面搭乘著已成為布朗夫人的克拉拉，還有他們的兩個孩子。博士告訴馬蒂和詹妮弗，未來是不確定的，現在的努力決定著將來的收獲，所以他們要靠自己來創造一個美好的未來。隨后布朗一家向他們的朋友告別，博士的時光機變形后騰空而起，向著未知的時空呼嘯而去。
