A college student (Ashton Kutcher) discovers a way to travel back in time to his troubled childhood as himself at that age. His goal is to change his life by changing painful events from his childhood. He finds that a very small change from his childhood will dramatically change his life today. He is not pleased with the results of his first trip back, so he makes another trip to change another bad event, hoping for a better life. Unfortunately, he must return to his childhood many times, because his alternate future gets worse with each trip. Where his life ends up is anybody's guess. Douglas Young (the-movie-guy).

The butterfly effect is a phrase that encapsulates the more technical notion of sensitive dependence on initial conditions in chaos theory. Small variations of the initial condition of a dynamical system may produce large variations in the long term behavior of the system. So this is sometimes presented as esoteric behavior, but can be exhibited by very simple systems: for example, a ball placed at the crest of a hill might roll into any of several valleys depending on slight differences in initial position. Source: Wikipedia.

The "Butterfly Effect" is the propensity of a system to be sensitive to initial conditions.Such systems over time become unpredictable,this idea gave rise to the notion of a butterfly flapping it's wings in one area of the world,causing a tornado or some such weather event to occur in another remote area of the world.

Comparing this effect to the domino effect, is slightly misleading. There is dependence on the initial sensitivity,but whereas a simple linear row of dominoes would cause one event to initiate another similar one, the butterfly effect amplifies the condition upon each iteration.
