At the beginning of the movie, a man drives a vintage Mercedes saloon to a gangster boss ("Der Gesundheitsinspektor" - The Health Inspector, played by Heiner Lauterbach). The "Health Inspector" enters the car, and is irate about loads of hamburger wrappers all over the interior. Obviously, someone ate a lot of hamburgers inside his car. The Health Inspector asks the man who it was, but the man is unable to answer, since he is obvioulsy severely injured and in pain. The Health Inspector switches on the car radio, which sets off a pre-installed bomb and the car, including both occupants, is completely destroyed.After this intitial scene, the actual plot commences, which took place the hours before the explosion and led to it.Leo (Til Schweiger) works as a hitman under the code name "Eisbär" (polar bear). He has decades of experience in his job and is a total professional. He has the order to kill a night club owner (played by German singer/songwriter Peter Maffay) and disposes off the body while talking to his mother on his mobile phone. He receives the message from the Health Inspector, that the person needs to stay alive, only after he had completed the mission. Threrefore, the thugs of the gangster boss are trying to track him down.Leo finds refuge in a delapidated pub called "Pauls Eck". Coincidentally, his 'collegue' Nico (Karina Krawczyk) is in the pub as well. She also thinks she has failed at a job.
