I stumbled on this film and that was a learning experience about practices such as devadasi en.wikipedia.org
and similar practices still going on in India

"Although the original devadasis were brahmacharis their entire life, even the contemporary sexual aspects of the rituals that accompany dedication are now considered by many Hindus to be exploitative and not mandatory. Nevertheless this practice continues unabated in some places where a devadasi would usually acquire a "patron" after her deflowering ceremony."

The girls picked up for the ceremony, like in the film, are only 13 years old.

Director Digvijay Singh paints a gripping portrait of pain in this controversial but thought-provoking movie that dares to expose the horrors of sexual exploitation of young girls... and not only girls from what's considered the lower castes, but also those from middle class families.
