The Butterfly Effect

Psychological thriller starring Ashton Kutcher as Evan Treborn, a young man who, from an early age, has struggled with his disturbing childhood memories.

As a boy, Evan was encouraged by a psychologist to keep a journal detailing the events of his day-to-day life, and now, as a young adult, he revisits these journals to figure out the truth about events that ended in tragedy for his childhood friends Lenny (Elden Henson) and Tommy (William Lee Scott), and the childhood sweetheart Kayleigh (Amy Smart) with whom he is still in love.

Evan makes the incredible discovery that he can use the notebooks as a vehicle enabling him to journey back into the past so that his adult mind occupies the body of his childhood self.

He begins a series of attempts to re-direct history with the aim of saving his friends and loved ones from the traumas that have befallen them.

But every time Evan changes something in the past, however small, he finds when he returns to the present that his actions have had unexpected and disastrous consequences.

The harder he tries to make things go right, the less able he seems to create a reality that allows him and Kayleigh to live happily ever after.
