Doc explaining Marty how the time machine works.
Marty McFly is a regular teenager who lives in the city of Hill Valley, California. But his family is anything from regular. His father, George McFly, is a wimp and gets bullied by his supervisor Biff Tannen. His mother, Lorraine, is also a failure and so is the rest of the family. One night Marty’s friend, Dr. Emmett Brown, who is also a scientist, calls Marty and tells him to meet him. He shows him his latest experiment, a time machine made out of a DeLorean. Marty then accidentally uses the time machine to travel 30 years back in time. Of course here he meets his pathetic father, still being bullied by Biff. After Marty runs into his teenage father, he secretly follows him home. As George is about to be hit by a car driven by Lorraine’s father, Marty pushes him out of the way and takes the hit himself. This results in Lorraine starting to fall in love with Marty instead of George, which is what was supposed to happen. After many uncomfortable moments with his teenage mother, Marty leaves Lorraine’s home in search of Doc. After he finds his house he convinces Doc that he is from the future and that he needs his help to get back to the future.
Through the course of the movie the relationship between Marty and Lorraine gradually gets worse and Marty desperately tries to get his parents back together. All the while, his brother, sister and himself are slowly being erased from history, which is shown by the photo of the three that Marty keeps with him. He must get his parents together or he will cease to exist. And while he does this, he needs to try and avoid the local bully, Biff who is always there to somehow ruin Marty’s plan. Meanwhile Doc is hard at work, figuring out a way to fix the time machine and get Marty back to the future before he messes anything else up in the past.
