De Stem des Bloeds The Voice of Blood, also known as Njai Siti, is a 1930 film from the Dutch East Indies now Indonesia. 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 stepdaughter unwittingly fall in love. The blackandwhite film, which may now be lost, was tinted different colours for certain scenes. It was released in early 1930 to commercial success, although critical opinion was mixed.
Fifteen years later, after his wife dies, van Kempen and Ervine return to the Indies. He has been hired as a supervisor at another plantation, not far from his old place of work. He searches for Siti and the couples children, but none of his old coworkers know where they are. Unbeknownst to van Kempen, his children have been raised as natives and wear the traditional clothes, although they have also received a Western education. Adolf has become a hunter, while Annie stays at home with their mother. Frederick, the new manager at Ciranu, has meanwhile fallen for Ervine and tries unsuccessfully to woo her.Some time afterwards, as Ervine is wandering through the woods she stumbles upon a deer and, startled, faints. Adolf comes across her and brings her back to the plantation, where van Kempen recognises him and takes him on as a supervisor. Frederick, however, is jealous of Adolf and Ervines relationship and entices the workers at van Kempens plantation to go on strike until Adolf is fired. Although heartbroken, van Kempen must fire his son. ........
