In Berlin for a conference, scientist Liam Neeson is travelling in a taxi driven by illegal immigrant Diane Kruger when it is involved in an accident.

He’s in a coma for four days but, when he wakes up, his identity has been stolen. His wife (January Jones) doesn’t know who he is, while another man (Aidan Quinn) claims to be her husband.

So ideally cast Neeson gets into action-man mode to find out the truth.

This exciting – if implausible – conspiracy thriller races full-pelt towards a surprise plot twist and a splendidly satisfying climax.
