The hero of the novel, Marty McFly, a college student, by chance travels through time. Jumping from the 80s to the 50s, he meets his parents. The hero's seventeen-year-old mother falls in love with an alien from the future - her own son. Marty understands: if the marriage of his future parents is upset, he will never be born. This story took place in October 1985 in the small Californian town of Hill Valley. However, few of the residents of this quiet place had any idea what had happened, since the only witnesses to these incredible events were only their participants - Marty McFly, Dr. Emmett Brown and a big shaggy dog named Einstein. But first things first.
