A biochemist and his dishy wife arrive in Berlin for a conference at which a scientist and his controversial Arab funder will announce breakthrough research. While
his wife checks into the hotel| he grabs a cab to return to the airport for his briefcase| left at the curb. En route| an auto accident puts him in a coma| from
which he awakes four days later without identification and with gaps in his memory. He goes to the hotel: his wife refuses to recognize him and another man has
claimed his identity. With help from a nurse| the cab driver| a retired Stasi agent| and an academic friend| he tries to unravel what's going on. Is the answer in
the briefcase?
Liam Neeson elevates the proceedings considerably, but Unknown is ultimately too derivative -- and implausible -- to take advantage of its intriguing premise.
