Sharmeen Obaid-Chinoy Wins Academy Award For 'A Girl In The River: The Price Of Forgiveness.'

LOS ANGELES — Pakistani-Canadian filmmaker Sharmeen Obaid-Chinoy has won an Academy Award for best short documentary.

The 37-year-old director claimed her second career Oscar for "A Girl in the River: The Price of Forgiveness.''

The film examines the case of an 18-year-old Pakistani girl who survived a brutal attack by her father and uncle bent on an "honour killing.''

"A Girl in the River'' is the latest in a series of socially charged investigative films from Obaid-Chinoy's Karachi-based film company SOC Film.

She previously won a documentary short Oscar for "Saving Face'' in 2012, about acid attacks.

"A Girl in the River: The Price of Forgiveness'' is set to air on HBO Canada on March 7.

"This is what happens when determined women get together,'' a triumphant Obaid-Chinoy declared to cheers from the celeb-studded crowd.

"This week the Pakistani prime minister has said that he will change the law on honour killing after watching this film. That is the power of film.''

"This is what happens when determined women get together.''

Before the bash, Obaid-Chinoy said she was grateful to see the Oscar nomination spark discussion around religiously motivated murders.

"I think that that's a win in itself because it's such a difficult topic and people shy away from it, normally,'' said Obaid-Chinoy, a dual citizen who lived in Toronto from 2004 to 2015.

Her competition included Toronto-based journalist Adam Benzine, up for his short film "Claude Lanzmann: Spectres of the Shoah.''

Obaid-Chinoy's other accolades include a Queen Elizabeth II Diamond Jubilee Medal, a Crystal Award from the World Economic Forum and a state honour from the Pakistani government.
