In this documentary, Canadian writer Michael Ignatieff travels to Croatia and Serbia to define the meaning of nationalism in the former Yugoslavia. Nationalism is a dream to be a master in one's own house, but it brings out the worst in people. He visits the highway of Brotherhood and Unity connecting Croatia and Serbia, Jasenovac (concentration camp during WWII held by fascist Croatia), Serbian enclaves in Croatia, destroyed Vukovar, and Belgrade. Archival footage used. Also, civilians and soldiers from both sides interviewed.
