Some people want to forget the past. Others want to change it. Evan Treborn (Ashton Kutcher) ties his emotional scars in adulthood to the frequent blackouts he had as a child. As he begins to unravel intensely personal truths about his childhood circle of friends, he decides to risk everything in a bold attempt to change the past, hoping to save the people he loves even if it means destroying everything he knows.
