Synopsis

After years of drifting around, Willi Palko arrives in the lignite mining area. He was not only looking for a new job, but also wanted to finally settle down here. The party leadership sends him to the Schepp brigade, which has made itself "suspicious" (on paper) due to its extremely high production figures. The stranger is accused of being a spy for the factory management. Willi finds it difficult to assert himself, but he is taken with the big excavator, the prospect of one day being allowed to drive it, and the brash flapper Hanna. He stays, and with his help a mine foreman is exposed as a Western agent and coal production is brought up to a really high level.
