Etienne Lantier, an unemployed railway worker, is a clever but uneducated young man with a dangerous temper. Forced to take a back-breaking job at Le Voreux mine when he cannot get other work, he discovers that his fellow miners are ill, hungry, and in debt, unable to feed and clothe their families. When conditions in the mining community deteriorate even further, Lantier finds himself leading a strike that could mean starvation or salvation for all.
