Sigi, der Straßenfeger(1984)

Street sweeper Sigi finds a box containing not only 300,000 marks, but also a photo of his unsympathetic superior in a compromising situation. Sigi thinks he's in luck, but what he doesn't realize is that an unscrupulous businesswoman wanted to use the money to bribe influential men. And of course she wants her money back. So the good-natured Sigi becomes embroiled in a series of turbulent adventures.
