Film shows real faces of 'comfort women'

After decades of living in silence and shame, so-called comfort women - who were sexually exploited by the Japanese military in World War II - have been given a face in a new documentary that gives firsthand accounts of their brutal experiences during a horrific chapter of history.

The film, The Apology, recounts the personal ordeals of three women - Grandma Gil in South Korea, Grandma Cao in China and Grandma Adela in the Philippines.

"For me it's important to give them a face, so they can share what they want to share and also teach us, the younger generation, about history, as well as what their lives were like after the war," said Tiffany Hsiung, who wrote and directed the film.
