A Hungarian doctor, Dr. Hajnal, who always considered himself out of politics, falls in love with the Soviet intelligence agent, the radio operator Alba, operating in the occupied Wehrmacht of Hungary. By accident, the radio operator is hiding in the doctor’s house. Hainal is drawn into a life-threatening confrontation with the Germans. A difficult question arises before him: to remain neutral when people die around and Alba is threatened with death, or to remain an honest person — to make his personal choice and take part in this struggle.
