Bruno Kamenar is a pale and thin ten year old boy who lives with his stepmother and younger brother in Croatia in 1948. His father, Pero, has just returned home after serving in the Yugoslav Federal Army. With the constant threat of a Soviet invasion serving as a backdrop, Bruno is plagued by frequent nightmares as well as a cough. He finds solace both in drawing and in the company of the family cow.
Sadly, Bruno contracts tuberculosis from the cow's fresh milk. At first he is unable to be treated because the government rejects an offer of free streptomycin from the Swiss. It is only after Pero publicly criticizes his country's refusal of medical aid and becomes a political prisoner that UNICEF physicians arrive at Bruno's home and treat him with streptomycin and PAS.
He recovers and his father is released from prison. As he watches the family cow and its pen incinerated, Bruno is filled with horror and relief by the death of an animal that once provided food and comfort but almost killed him.
