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.

Gosho Kalimanski, a clerk living the big city, finds difficulties to stand the endless noise around him.

Boris Morev dreams of money and power, he’ll do everything to reach the top, including leaving his beloved Irina, to marry the daughter of the local tobacco factory owner. With the death of his father-in-law and the illness of his wife, Morev becomes the new owner of "Nicotiana" and rules with an iron fist, resulting in massive labour strikes and murder. He ropes Irina back into his life, first as a mistress and later as his second wife, but his ambitions still come first as he plans on emerging as the biggest tobacco seller once the war is over. Irina’s love for Boris is fading and she finds a lover in one of the Germans Boris is trying to strike a deal with. Set against the backdrop of World War II and communist partisans fighting against the Nazi-allied Bulgarian monarchy, the film is a screen adaptation of the Bulgarian classic novel "Tobacco" released in 1954.
