1972. Once hearing the songs of Robertino Loretti, a 12-year-old schoolboy from Lyubertsy Yura also begins to sing. At first, he is shy about this, because singing, according to his peers and some adults, is not a man's occupation at all. But, thanks to the mentorship of a young music teacher Varvara, Yura develops her talent and decides to audition for the Pavlov Choir. The head of the choir has only a month to expand the cast and prepare a new program for participation in the TV festival "Song of the Year".

Bear buddies Bucky and Bjorn play games, go on far-out adventures and learn about wondrous new things together.
