Just Married and Dude, Where's My Car? goofball Ashton Kutcher takes on a more serious role in this ambitious supernatural thriller. Written and directed by Final Destination 2 scribes J Mackye Gruber and Eric Bress, it's based on the idea of chaos theory, which speculates that the smallest of events can have the hugest of consequences. In a plot that feels lifted from The Twilight Zone, Kutcher plays a troubled college student who discovers he has the ability to go back in time and rewrite the past. Touching on provocative themes such as child abuse, disability and terminal illness, Gruber and Bress have created a powerful and disturbing tale. Despite being spoilt by a rushed and overly simplistic conclusion, it's surprisingly dark and adult for a Hollywood project. In contrast to his joker reputation, Kutcher delivers a strong and believable performance, though his co-stars, with the exception of a stomach-churningly good Eric Stoltz, are largely unremarkable.

A young man struggles to access sublimated childhood memories. He finds a technique that allows him to travel back into the past, to occupy his childhood body and change history. However, he soon finds that every change he makes has unexpected consequences.
