The orphan Eliška Irovská, nicknamed Líza, arrives in her native village of Ptačice. As an orphan she is housed in the local poorhouse and has to go out begging. Her guardian Petr Tumlíř, however, sees that she is competent enough to go to school.

Zdenka Sulanová has grown from a leggy frog into an attractive young lady in the two years since the success of Líza's Flight to Heaven. It is no wonder that Václav Binovec decided to guide her through the further pitfalls of the life of the orphan Líza, who comes to a monastery boarding school to gradually win the heart of a strict teacher, her classmates, and finally the man who caught her eye at first sight. Of course, it will not be easy and Líza will have to shed a few secret tears, show vitality and a willingness to fight for her happiness. Then even the viewers of this typical First Republic girl's romance can conclude with emotion that the world is not so bad after all, when a poor girl can achieve success in it through diligence and hard work.
