Back to the Future

In 1985 Hill Valley, California, teenager Marty McFly and his girlfriend, Jennifer Parker, are chastised by the school principal for lateness. Marty auditions for the Battle of the Bands, but is rejected for being too loud. At home, Marty's father George is bullied by his supervisor, Biff Tannen, while his mother Lorraine is an overweight, depressed alcoholic. Lorraine recalls how she met George when her father hit him with his car.

Marty is invited by his friend, eccentric inventor Dr. Emmett Brown, to meet him in a parking lot in the early hours. Doc unveils a time machine built from a modified DeLorean and powered by plutonium stolen from terrorists. Preparing to demonstrate the time machine, Doc sets the date to November 5, 1955: the day he invented time travel. The terrorists arrive and shoot Doc. Marty escapes in the DeLorean, but inadvertently activates the time machine.
