Ok. Check it out.
There are four specific years that you must remember: 1885, 1955, 1985, 2015.
No, really, this is neat! This is a story that explores the fabric of reality. It touches on the very core of things – of everything!
Currently, it is 1955 and you’re seeing the Marty from 1985 and the Doc Brown of 1955. With the help of this Doc Brown from 1955, Marty must travel back to 1885 to rescue to the Doc Brown from 1985, who was accidentally struck by lighting in this 1955; thus overloading the flux capacitor in the DeLorean time machine that was hover-converted in 2015 – yes, 2015.
Well, here’s what happened – At the beginning of the second/previous movie, the Marty from 1985 had just gotten back to 1985 after being trapped for a week in 1955, all with the help of the Doc Brown from 1955. So, the Doc Brown from 1985 came blasting in with the DeLorean all in a tizzy about Marty coming back to the future with him – back to 2015. Still with me? So, Marty and Doc Brown from 1985 go back to 2015 to keep Marty’s son from joining the grandson Biff (the trilogy’s bad guy(s)) in a robbery. While in 2015, Marty buys a sports almanac with the intent of placing bets once he and Doc Brown get back to 1985. The catch is that the grandpa Biff of 2015 obtains the almanac, sneaks off with the DeLorean and travels back to 1955 to give the book to his teenage 1955 self.
Here’s where things get dicey. At length, Doc and Marty from 1985 return to 1985 from 2015, only to find that this 1985 is an alternate version of their home time of 1985. In this alternate 1985, Biff is rich and powerful and the head tyrant of a mass dystopia. This fortune was made overtime because of the successful delivery of the sports almanac from the Grandpa Biff of 2015 to the teenage Biff of 1955 in 1955. So now, in order to correct this tragedy, Marty and Doc from the home time of 1985 leave this alternate 1985 and go back to 1955 to reclaim the sports almanac from the teenage Biff of 1955; but only after the Grandpa Biff of 2015 returns the DeLorean to 2015 to help prevent two time machines being in 1955. The problem is that this story now overlaps with the story of the first movie – where the Doc from 1955 is helping the Marty of 1985 get back to 1985, not the alternate 1985. If the Doc from 1955 were to see this Doc from 1985, and if the Marty from 1985 were to see… the Marty from 1985, Doc predicts that…
…the encounter could create a time paradox, the results of which could cause a chain reaction that would unravel the very fabric of the space time continuum, and destroy the entire universe! Granted, that's a worse case scenario. The destruction might in fact be very localized, limited to merely our own galaxy.
Yes, I have that memorized. Yes, he actually says it like that.
No, hear me out. Really, it’s a really cool story.
Fine, change the channel.
