Dr. Martin Harris (Neeson) wakes up after a car accident in Berlin, only to find out that someone has assumed his identity, his wife doesn't recognize him, and he is being pursued by assassins. In order to figure this out, he enlists help from a couple of people and, in the process, he figures out who he can trust and who he can't.
I am a big Liam Neeson fan...he has a knack for picking excellent scripts that are taylor-made for him.
There is plenty of action, the suspense is constant, and the chase scenes are among the best I've ever seen.
Two words: See it!
