A man claiming to be Dr Martin Harris awakes in Berlin hospital with severe head injuries and very little knowledge as to how he got there. Attempting to piece together his fractured life, Martin discovers that his wife no longer recognises him and another man has assumed his identity. But that is not the end of the Doctor’s problems; he’s also being hunted down by a team of assassins. Unknown is a stylish dramatic thriller but don’t expect the high kicking antics of ‘Taken’ regardless of the cover tag lines.
