A short promotional film challenging the traditional view in India that a married daughter must stay with her husband in their marital home - even if he is abusive - has spotlighted domestic violence and won hearts across the country.

The three-and-a-half-minute Band Baaja Bitiya - Hindi for "a wedding band and daughter" - is the moving tale of a father who goes to retrieve his daughter from her violent matrimonial home and uses the celebratory wedding band as a mark of defiance.

The film starts with the father, played by veteran Bollywood actor Gajraj Rao, receiving a phone call from his daughter Surabhi.

"Again?" he asks, the pained expression on his face reflecting the troubling news he's just heard.

The advice he receives from family and friends is typical. "It's her home, her fate." Or, "tell her to adjust." "A little bit of shoving and pushing" is "no big deal" in a marriage. Once Surabhi has a baby, "things would sort themselves out".
