We see the Katics at the dawn of World War II, in Belgrade. Bogdan Dragovic has returned from emigration, trying, for the sake of his son Vladimir, to re-establish ties with the Communist Party from which he was expelled as a Trotskyist. His virtually abandoned wife, Milena, becomes emotionally involved with Petar Bajevic, Comintern's agent and Bogdan's war buddy. Milena and Bogdan's son Vladimir, now a member of the Communist Party himself, turns against his father for ideological reasons. Milena and Ivan's father Vukasin is an epitome of civic Yugoslavia and its principles, which fails to resist the invasion of the oncoming circumstances and ideologies. The Second World War breaks out, Milena and her brother go to Prerovo, Vladimir joins the partisans, while Petar and Bogdan end up in the Gestapo at the same time.
