In this routine World War II drama by Bulgarian director Doutcho Mundrov, a group of doomed POWs work together to keep their own dignity and ethical standards high. As the prisoners interact against a background of strife, imprisonment, and references to a rising Communist presence, they come to discover that there is an outside informer passing on information to the enemy. Although they face impending execution, they decide to take steps to end the informer's career.

Nine volunteers begin digging a tunnel through rugged mountain terrain. The group includes three miners. The others have come from different parts of the country for different reasons. When winter comes, a blizzard makes the road impassable and the truck with supplies cannot reach them in time. With only a hundred metres to dig, the tunnel collapsed. Everybody leaves the construction site, except the communist Damjan. In town they check in at the mine and are due to start work in two days. During these two days, one by one, they are overwhelmed with shame for leaving the tunnel, and finally return to Damjan to finish their work despite all the difficulties.

A geologist engineer Yuliya disappears. Ablamov, an elderly engineer, organizes a rescue party to look after her in the mine galleries but they find nothing. Yuliya was last seen at a ceremony for award-wining miners. The newsreel crew was filming the event. Yuliya left in the middle of ceremony. Prodanov, a headstrong and quarrelsome engineer, had followed her. Suspicion falls on him. However, the film sequences shot at the ceremony reveal that Ablamov reacted suspiciously to Yuliya's exit. Detected as the murderer, Ablamov attempts to cross the border but is caught. Yuliya had discovered that the ore contained uranium. Ablamov had replaced the samples in order to prevent the development of the uranium ore deposit.
