Thirty-year-old Piotr Alekseevich Marakulin lives a contented, if humdrum life as a financial clerk in a Petersburg trading company.

This change of status brings him into contact with a number of women--the titular "sisters of the cross"--whose sufferings will lead him to question the ultimate meaning of the universe.
