In this 1980s sci-fi classic, teen Marty McFly is accidentally zapped back to the 1950s by his mad-scientist friend, Doc Brown. Armed with only a time-traveling DeLorean and awkward teen energy, Marty must make sure his young parents fall in love—or risk disappearing completely. Oh, and he also has to figure out how to get back to the '80s and save Doc from a very bad day. No pressure, right?
