A little girl, big challenges and an even bigger heart.

It’s been a while since the last movie about Paulina P. and our heroine is now already eleven years old! Although the adults keep telling her that this is the “best part of her life”, it doesn't seem like that at all to Paulina. In the fifth grade, she will have to face professor Mirković, a strict and indomitable geography teacher, as well as Marta from the class 5D, Paulina’s first bully. As if that were not enough, she will soon discover that her dear grandmother Ljerka suffers from an unusual and incurable disease. Fighting the troubles that life brings, Paulina will once again use her strongest weapon, charm and vivid imagination, but also learn a valuable lesson – that life is not only about winning.
