Eroica is a memory, or rather the memory of childhood, the transition from childhood to adolescence, the end of a heroic era. The Eroica tells the story of a group of children in an unspecified city at the beginning of the century and their adventures. Fifty days is the time period in which the events unfold. Fifty days that have the scope of an entire life, for this reason it simultaneously encounters joy and sadness, celebration and mourning, love and death, the beginning and the end.
