According to the story, Dr. Emmett Brown invented a time machine for 30 years, and finally, in 1985, he finished work on it, installing an energy flux generator (in other translations - a streaming drive and a flow condenser) in a DeLorean car.
First, he demonstrates the car to his young friend, high school student Marty McFlay, but it is then that they are attacked by terrorists hunting for the Doc. Doc is killed, and Marty saves time in a car and gets in 1955. Returning is extremely problematic, because plutonium is needed to travel through time. In addition, because of the absurd accident, Marty prevents his parents from meeting. Emmett Brown, hoping with his help to solve these two problems, and also to save Doc in the future, warning about the danger. Marty must have time to fall in love with each other's parents, confront the bastard Biff Tannen and return in due time.
