In May 1945, a broken violinist lies drunk by a creek, haunted by memories of his life before and during WWII. Once the celebrated first violin in spa orchestras, he married Jewish nurse Róza and dreamed of fatherhood, only to face brutal anti-Jewish persecution. Relegated to second violin, he spirals into alcoholism and betrayal, while Róza and their daughter are deported.

In a final psychotic haze, he tends a roadside Christ statue before collapsing, his shattered life a testament to love, loss, and atrocity.

The subject of this film, which takes an analytical look at the life of all of us with an analytical eye, is the evil microbe that has slowly infiltrated the organism of the Czech nation.

The bleak conclusion suggests that the plague epidemic is still ongoing.
