Two decades ago, a wall was built in a small primary school in the Kosovo village of Rubovce, twenty kilometers south of the capital, Pristina. It still remains in place today. The wall separates Albanian and Serbian students who enter the same building every morning, yet never play or talk to one another, neither during classes nor breaks. Both students and teachers have learned to live in two parallel worlds, and don’t seem to mind. Neither side is interested in taking the first step towards changing the situation. Director Nikola Polić and cinematographer Husamettin Luma use their probing camera to expose the persistent mechanisms of ethnic segregation at the grassroots level.
