Two crash pilots from BravoAir have to fight crime with their dim-witted mechanic, the beautiful daughter of a beaten-up police inspector, and the mechanic's 15-year-old godson. Not only are the three of them and the little one clumsy, but so are the gangsters and the police.

Because her husband, crime novel author Bert, prefers to spend the evenings with milieu and girl studies in the pubs, Conny files for divorce and moves with the two children from Berlin to Munich. There, she mistakes the new teacher of her daughter with the renovating carpenter, which is quite alright with the teacher as this gives him plenty of opportunity to enjoy Conny’s company. Meanwhile, however, Bert as well has started to understand how good it is to have a cosy home. He comes to Munich in order to win Conny back.
