World champion boxer Manny Pacquiao has had more than 50 professional fights. But none may be more important than the battle he has joined against the trafficking of tens of thousands of women and children.
Pacquiao, who is also a lawmaker in his native Philippines, teamed up with campaigner Cecilia Flores-Oebanda, who has spent 20 years trying to protect victims of sex slavery and forced labor.
CNN spent two years documenting her struggle as she enlisted the help of Pacquiao. The resulting full length film premieres on CNN International on May 17 and 18. Watch the trailer here.
