De Stem des Bloeds, also known as Njai Siti, is a 1930 film from the Dutch East Indies. It was directed by Ph. Carli and starred Annie Krohn, Sylvain Boekebinder, Vally Lank, and Jan Kruyt. The film follows a man and his mistress who reunite after their son and step-daughter unwittingly fall in love.

After the death of her husband, Christine realizes she has possibly wasted her life by marrying him instead of the man towards whom, in her youth, she had a stronger inclination. To overcome these dreary thoughts, she decides to find out about him and the other men who danced with her during a ball that was a turning point in her life, many years ago. She pays a visit to those forgotten acquaintances one after the other; Christine is not only surprised to see how they have fared, but also discovers the impact she had, unknowingly, on the feelings and the destiny of these persons.
