The soccer team of the company sports association "BSG Hartenfels" is going downhill. New training methods - based on scientific findings - are needed, says Paul Schmidt. But he runs up against the star striker Wieland, whose friends naturally stick by him. So water sportswoman Ruth, deputy chairwoman of the BSG, decides to use female cunning to change the situation for the better. She and her friends Lilo and Uschi want to "work" the unruly ones. In the end, there is indeed a victory - on the sports field - and two happy couples.
