An extensive documentary of the band narrated by Tom Angelripper, featuring interviews to current and ex-members, rare pictures and video footage.

Dennis, an American private eye, is sent to Germany to find out as much as possible about typical Germans and typically German behaviour. Disguised as a TV reporter he sets sail for Germany where we follow him interviewing a wide variety of people, from politicians and intellectuals to policemen, demonstrants and ordinary people in the street. All this, however, is not what the film is really about, for "Deckname Dennis" is actually a satirical documentary about all those extremely odd people, groups and societies whose attitudes and behaviour are far too outrageous for anybody to take seriously. Therefore ALL the documentary bits are real, i.e. the people really thought they were being interviewed by an American reporter, and so they gladly presented an insight into their beliefs, ideas and goals.

The young policeman Joachim Krippo likes to occasionally share his bed with a nice married couple. When he is supposed to be guarding the criminal Engel Potraske during a court appearance, the dangerous Engel manages a spectacular escape, but departs minus a toe! Krippo is subsequently suspended from his duties and put with other police officers under the care of an elderly police psychologist. Krippo's professional set-backs are followed by private ones: his grandad - who was actually being well looked-after in an old people's home - is dropped off at his place because the payments due have not been made. He tries to get his grandad out of the flat by pairing him off with the police psychologist. But, in the critical moment, Krippo lunges for the bait himself. At least, this means that he will be discharged from the psychograph tests as being fit for service again...

Two people love each other when they know they should not. Their parents' and friends' pleas, their social backgrounds and reputation, their careers; everything is used to make them give each other up. Flattery, lies and threats finally drive Frank to despair and Karin to treason. But it is not due to their parents' hatred, nor to any greed for inherited wealth. Rather, the mere conjecture expressed by the authorities is enough to set off a merciless mechanism.
