A group of soldiers is supposed to ensure the smooth nighttime passage of the military convoy through Prague, but things turn out differently. Eloquent young men convince the good-natured commander to sign a leave of absence, and the main character is left alone in the middle of a housing estate...

It is the summer of 1945. A party of young people are enjoying the beginning of a new life to the full. For them this is the year one. One of them, law student Pavel, is more attracted to film than to law. With his eight-millimeter camera, he films everything that catches his attention. One day he captures an interesting face on film, a girl with an air of mystery. Pavel visits the girl, whose name is Helena, and meets hers and her elder energetic sister Olga. From Olga, he learns that the girls have spent the years of German occupation in a concentration camp and cannot forget the horrors they have lived through.
