A Polish tale of a young girl, her new friend and his dog trying to retrieve a long-lost Picasso mural from a derelict house.
Friendship is not easy and Julia knows it. She is 12, attends a boarding school and has never had a real friend. The start of vacation brings trouble. Instead of joining her parents in Canada, Julia ends up at her aunt's in Warsaw. There she meets Olek. Together they find a treasure map and so adventure begins. To solve the puzzle and defeat the gang of nannies-thieves, Julia has to do something she has never dared: trust a friend.
