You and Doc have barely recovered from the first time-travelling adventure when you launched yourselves once more into the space-time continuum. But this time around, the attempt to fine-tune the future in the year 2015 creates an outlandish, alternate 1985 Hill Valley where bully Biff Tannen is rich, powerful and... your dad! Now, your only chance to fix the present is by going back to 1955 all over again. But can you and Doc patch up the past without igniting a universal-shredding time paradox?

BONUS NOTE:

You will need to edit this ALOT to make it perfect to fit the movie-accurate plotline. I've tried to make it as close as I can on my end in the starting point. For where it starts, I've made it fit RIGHT to the beginning, so right after you (aka: Marty McFly) would have seen the Toyota Hilux, and almost given Jenifer her kiss before Doc appeared with the newly upgraded and hover-converted 2015 DeLorean.
