Shivers is set in the early 1950's, during Stalin's Personality Cult. The story opens in a provincial town where Tomek's father, a former member of the Home Army, is arrested. This leaves Tomek's mother with the task of raising two kids alone.
The neighbor upstairs commits suicide when her husband is also arrested and transported to the prison camp. It's winter, so the kids keep their hands warm at school by hand-beating themselves. The teachers at school are mean, narrow-minded idealists.
When they ask the kids who goes to church on Sundays, the whole class stands up to defeat the purpose of the propaganda lesson. Tomek is sent to the training school in the summer, where he absorbs most of the ideology pumped into his head.
When his father is released from prison, he finds another boy he has left.
