The Butterfly Effect

“Change one thing. Change everything.”

Evan Treborn (Ashton Kutcher) is a college student plagued by blackouts from his childhood. He discovers he can travel back into his body at those lost moments and change what happened, each time returning to find his present world altered. Bress and Gruber build each revision as a small catastrophe, spiraling outward until Evan realizes every corrected mistake has shattered the lives closest to him.
