Act 3, Sequence 8: Back to the Future
In reconnecting the wire, Doc pulls apart the connection on the ground. While Marty speeds down the street, Doc slides down the wire and reconnects it. When the lightning hits, Marty is propelled back to the future. Unfortunately for Marty, the DeLorean stops running when he returns to his time, and he is still in downtown Hill Valley. He has to race to the mall to save Doc, but he is too late and watches the Libyans shoot Doc Brown again. Racing down to the scene after the Libyans crash into the photo booth, he discovers to his surprise that his friend is still alive. The Doc of the past taped together the letter Marty wrote, and future Doc took precautions by wearing a bulletproof vest. Doc takes Marty home and goes back to the future. The next day, Marty awakens to find that his entire family has changed. His brother and sister are successful, and his father and mother are hip, modern people who are very much in love. Also, George McFly has just received copies of his first book as an author and Biff has been reduced to a meek auto detailer. Marty even has his dream truck to take Jennifer on their weekend excursion. Then Doc reappears in the DeLorean. Marty and Jennifer have to return to the future with him to save their kids from harm. Only now, the time machine has hover capabilities they use as they blast back to the future.
