This is an automatically translated description

Petryk is the only son of a wealthy noble family, the Popelsky family, and has been blind since birth. His mother, Anna Mikhailovna, loves and pities the boy, and so she raises him like a fragile flower. His uncle Maxim, who fought under the Garibaldi banner in his youth, tries to teach Peter to be independent. The boy begins to learn the world by touch, and one day his fingers find the keys of the piano. Not yet knowing the value of his talent, he goes with the tramps to "search for the truth". Only love can now reconcile him with the world of the sighted. Translated from Russian by F. Havrysh.
