The Ghost actress headed to Nepal and India to work with campaigner Anuradha Koirala, who fights against the trafficking of women on the boarder between the two countries.
In the CNN documentary, entitled Nepal’s Stolen Children, Moore met with one woman who had been forced to work in a brothel, where her young daughter was also kept hostage. Police managed to save the mother during a raid, but did not remove the daughter.
Officials eventually did rescue the young girl, and Moore was witness to their reunion - but was left in tears when the girl failed to recognise her mother.
Moore says, "As a mother of three girls myself, it was painful to watch, and everyone in the room feels helpless".
The documentary aired on Sunday (26Jun11).
The Ghost star is an outspoken activist against slavery and trafficking and has teamed up with husband Ashton Kutcher to form the Demi and Ashton (DNA) Foundation, which aims to stop the practice.
Now Moore is fronting a documentary titled Nepal's Stolen Children, in which she visits last year's (10) CNN Hero of the Year Anuradha Koirala to discuss how she is helping women who have been forced into prostitution.
In the TV special, which was made in partnership with the CNN Freedom Project, the actress also meets a number of trafficking victims and is heard asking how one girl, Tulli, ended up becoming a sex slave.
The programme is due to premiere worldwide on Sunday (26Jun11).
