Watch HDToday. Nena recently started working as a school assistant to seven-year-old Dejan who has learning disabilities. It's one of the first Nena's grown-up jobs, and Dejan is a tough cookie so every day is a new challenge for the two of them. Apart from that, Nena also has to struggle with the rigid school system around them. Things look pretty bleak until one day a fluffy white friend comes to visit.
