"Anna" was just 20 years old when she was captured in 2011 by two armed men in London. Taken to Galway, Ireland, she was tortured, locked up for four months and forced to be a sex worker. "I didn't see the colour of the day, I just knew the time was passing and I couldn't count the days," she said. Anna worked in several brothels until one of her clients helped her escape. She is now helping the police track her captors and plans to study law to help other survivors.
