The firemen of a provincial Czechoslovakian town throw a ball in honor of the old chief's retirement. There will be music and dancing, a beauty pageant and a raffle. The whole town will be in attendance. However, the proceedings are dogged by difficulty at every step. Workplace injuries, stolen prizes, a shortage of pretty girls... and fire.

An artist's studio is descended upon by a group of retired men and a young mother who agree to model in the nude for money. Comedy ensues as the students and the local bureaucracy react to the models, all in need of extra money. Several running gags border on slapstick as the officials and the students don't know what to do with the nude models.
