Are you 100% sure you are who you think you are?  That’s right, besides you "knowing" you are in fact yourself, how are you a 100% sure of that? Confusing, isn't it?

This film begins, when Dr. Martin Harris (Neeson), and his wife, Liz (Jones), arrive at Berlin with the purpose of assisting to a Biotechnology summit. When arriving at the hotel, Dr. Harris realizes he has lost his briefcase with his important and personal information in the airport. He desperately gets a cab to go back and recuperate his lost briefcase. Only he didn’t know that would be the worst decision of his life.  On the way to the airport, he is involved in a car accident, and ends up in the hospital, just barely making it alive. A couple of days after, he wakes up from a coma, and without the doctors approval goes back to his hotel, but only to discover that someone has stolen his identity. There is another man pretending to be him, and not even his own wife recognizes him.  Having lost his briefcase, which included his passport, and other personal files, that are his only way of proving he is in fact who he thinks he is at the airport when arriving at Berlin. And if you think those aren't enough problems yet, he is also being chased by some mysterious people that are trying to kill him. With the help of the cab driver (Kruger) who saved his life, and a private investigator, he is ready to prove everyone wrong, and get his life back.
