In this long-time favorite, eccentric inventor Doc Brown (Christopher Lloyd) turns a DeLorean into a time machine that inadvertently sends his young friend Marty McFly (Michael J. Fox) back to 1955. Not only is Marty stuck in the past, but he also risks throwing the time-space continuum for a real loop when he disrupts his parents\' destiny. It\'s a race against time (literally!) to get them to pucker up -- and to get him back to 1985!
