Things could truly be better for regionally successful entrepreneur Manfred Brenner in the mid-1980s. For Brenner, however, there is no reason to worry, because he is firmly counting on a breakthrough with his newly founded company FlowTex.  With innovative horizontal drilling systems, he wants to revolutionize underground pipeline construction. But at first  the big success remains elusive.  He finally succeeds by  relying on drilling systems and orders that don't even exist, piling up loan upon loan and leasing contract upon leasing contract. He uses charm and persuasion, and for a long time no one notices that Brenner is building a fraudulent consortium of companies with just a few helpers and a lot of falsified documents.

Big Manni

The gas station attendant at a Mainz gas station was shot. This is the second assault in two weeks, but this time it's fatal. The only witness is the blind law student Rosa Münch, who still lives with her parents and longs for a life beyond the overprotective control of her father. Chief Inspector Ellen Berlinger and her partner Martin Rascher investigate the traces of the two perpetrators and follow the indications of the blind: The smell of an expensive perfume, the voices of suspects, the details heard and felt by Rosa at the crime scene. The commissioners want to put the vulnerable witness under police protection, but the young woman refuses. On the contrary, when another unknown young woman, whose voice sounds familiar, tries to contact Rosa, she keeps it to herself. The experienced investigators suspect that Rosa knows more than she says, and have to continue investigating without their support and resort to unusual methods to prevent further deaths.

He keeps thinking about what his father had told him: "We have to dream as much as we can. How can all the wonderful things that could change the world become real if no one dares to imagine them?" On the last day of school, Paul picks up his father's notes and decides to go in search of the cave with his best friend. Thus begins the summer of their lives.
