DR Martin Harris (Liam Neeson) travels to Berlin with his beautiful wife Elizabeth (January Jones) to attend a biotech conference at the invitation of Professor Bressler (Sebastian Koch).
As they arrive at the hotel, Martin realises that he has left a briefcase containing his passport at the airport and he jumps into a taxi to collect it.
En route, there is a freak accident and Martin slips into a coma, waking four days later in hospital with fractured memories.
Discharging himself from hospital, he races back to the hotel and is delighted to find his wife... except Liz doesn't recognise him and another man (Aidan Quinn) with the same name is on her arm.
Suitably confused, Martin hunts down taxi driver Gina (Diane Kruger), who was involved in the accident.
With nowhere else to turn, Martin contacts former Stasi officer Ernst Jurgen (Bruno Ganz) to try to get some answers.
