Directed by Valentin Vaala, it is based on Frans Eemil Sillanpää's 1934 novel of the same title.

The film concentrates on the destinies of a small group of people during one summer night.

During the night people are falling in love, fighting drunk, dying, and being born.

The novelist Sillanpää himself had told Vaala to keep in mind that there should be only one main character, and that is the summer night.

They especially praised Eino Heino's cinematography, stating that such beautiful and sensitive capturing of Finnish nature had never before been seen in domestic films.
