Editor Eckernförde has come into the possession of an audiocassette that contains a recording of the last minutes of deceased politician Uwe Barschel. The circumstances of his untimely death have never been completely resolved - until now. Unfortunately, the editor's daughter Nina accidentally takes the tape with her to Munich, where she is about to visit her paralyzed Mom in a sanatorium. When this information reaches the CIA and the BND, both organizations compete to get hold of the tape. Meanwhile Erkan & Stefan, two loveable wannabe supercheckers from Munich, are assigned as bodyguards for Nina - of course, they are expected to mess up their job, so that the tape can be retrieved. But the two friends prove to be a bit more streetwise than CIA or BND ever expected.
After his daughter died of cancer, former French foreign legionnaire "Straight Shooter" alias Volker Bretz threatens those who financed, built, favoured and now work the nuclear power plant Atar II to kill one of them each day until the plant is shut down. His former drill sergeant, Frank Hector, who now owns several night clubs and brothels, is the only one who might be able to stop the maniac killing specialist. Frank is flown in instantly, but soon has to find out that his former comrade's actions might be a result from an event long ago.
