Klau, jau divas dienas Marty McFly klīst pa mūsdienām, un nevar saprast kur palikuši lidojošie auto ar atomdzinējiem. Kaut ko viņš tomēr nesalaboja savos laika ceļojumos.
http://en.wikipedia.org/wiki/Back_to_the_Future_Part_II On October 26, 1985, Doctor Emmett Brown arrives from the future and persuades Marty McFly and his girlfriend, Jennifer Parker to save their future children from getting into trouble. As they depart, Biff Tannen accidentally witnesses their departure. They arrive on October 21, 2015, where Doc electronically hypnotizes Jennifer and leaves her incapacitated in an alley. Meanwhile, Doc has Marty pose as Marty McFly, Jr., Marty's future son, to refuse an offer from Biff's cybernetically-enhanced grandson, Griff Tannen.
