Benjamin, un joven alemán genio de las computadoras, se une a un grupo de hackers subversivo que quiere hacerse notar en el escenario del mundo.

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.

El Servicio de Inteligencia Federal alemán convoca a Wolf para que evalúe si la información del informante, a quien se le ha otorgado el sobrenombre de "Curveball", es o no cierta.
