Although Lena does not live a carefree life like her peers, no sorrow can be seen on her face. Every day, she sells candied apples in front of the city ice rink to help her parents with the money she earns. It seems that the bitter poverty she lives in has left no mark on her pure and selfless childlike soul. Christmas is drawing closer and closer, and Lena has almost no wishes for herself. This has not gone unnoticed by a poor beggar who asks for some money. Selfless as always, Lena gives him her last red candied apples and her scarf to keep him warm. From that moment, it seems as if an angel has descended from heaven and finally looked upon the poor child and her loved ones. Early the next morning, her father Andrija, who works as a laborer, finds an unusual Advent calendar in front of their old dwelling. At that moment, no one suspects that behind the calendar's doors lies an extraordinary magic. But Lena does not want dresses and gifts; her small soul is burdened by deeply hidden pain and sorrow. Her wish is for her mother to recover, for her father to find a decent job, and for her to finally meet the grandparents who had turned their backs on them long ago in a quarrel. This Christmas will be one of those that will change Lena's life forever, and the Christmas star will finally illuminate their home with happiness.
