The Butterfly Effect

Evan Treborn discovers that he can access memories from his childhood by reentering his former body at key moments in the past. He experiments with a method that lets him slip through time and change events he once lived. At first the changes seem to fix painful moments, but as he alters the past the present around him shifts in unpredictable ways. Friends and family who seemed safe reveal new flaws, and the things he hoped to protect end up altered in surprising and troubling ways. Each alteration teaches him that messing with memory has a price and that some losses are harder to repair than others. As he tests the limits, he learns that even small changes can alter relationships, school memories, and his own sense of self.
