At the beginning, the newly arrived soldiers form a musical theatre troupe to escape the humiliation of the older ones. They vow that they will be good to the next recruits. But it turns out that nothing can be done without strictness and that greed is not some kind of deviant perversion. In this comedy you will find not only great musical numbers, but also a lot of gags from the military environment. It is also the first film in which the famous semaphore duo Suchý and Šlitr appeared.
