1970 film by Hans Heinrich

The girl Marianne inherited a motorboat called “Eintracht” from her parents and struggled to get her to drive it with her uncle. There is a row with the new engineer Michel the evening after the first trip. He leaves - out of jealousy. Instead of him, Marianne takes three funny musicians with her who are looking for work. The trip to Hamburg on the Elbe initially ends on a sandbank, from which another barge, the "Petrel", frees them. Michel has now been hired there. After a few complications and pointless fights, because Marianne has long been in love with Michel, there is the well-deserved happy ending.

The stubborn old skipper Heinrich Borchert refuses to recognize the progress of the new era. Sailing for the DSU is out of the question for him. He is a private ship owner - and will remain so! In order to pay off the mortgage on his barge "Marie", he takes more cargo on board than is reasonable and risks a dangerous draught in the shallow waters of the Havel. Neither his friend Hermann Vollbeck, also an old bargeman but sailing for the DSU, nor the protests of his son Karl can dissuade him. After all, Borchert is only doing all this for Karl, who is supposed to take over the boat one day and have a better life. He, on the other hand, has other ideas about life. Instead of just being a slave to the ship or having to deal with debts, he wants to have time for more enjoyable things alongside his work.
