If you like Liam Neeson, you will like this. The action is fast paced, and there is a plot twist that I admit i didn't see coming. I normally do twist coming, so being caught off guard means that the some thought did go into the story. Combine the action, story-line with decent locations and you end up with a very good film, if you haven't seen it, you should.
We have Liam who plays a biochemist that wakes up from a coma after being involved in an accident on the way to a conference in a foreign country. Liam manages to remember which hotel he and his wife checked into, so he goes there only to find another man pretending to be him. Worse still is that his wife also says she doesn't know him.
The only people that believe him are a taxi driver and a nurse, so now he is on the hunt to find out why no one from his life will acknowledge his existence. He also needs to find proof that he is he and explain some of the specialized skills he seems to have.
