This film is a psychological thriller based on a man who wakes up from a coma in Berlin to discover that his wife doesn't know who he is. His briefcase has been left at the airport and he has no records or passport to prove who he is. He pays a private investigator to help him find out who his impersonator is and why, and makes a friendship with the cab driver who is an illegal immigrant. There is a huge fight at the end of this film and all is revealed.

I believe that this is a very good film with a clever plot. There are many different techniques used throughout the film to create the thriller and they are very effective.

Different camera shots are used in this film. Flashbacks are used throughout the film which I think is a good convention of a thriller and is very effective. This tells the story backwards.
