Daryl HannahDaryl HannahIt's a big, bad world out there and Daryl Hannah can vouch for that.

She's revealed a horrifying past experience, which still haunts her today...

She narrowly escaped being sold as a sex slave in the late seventies.

And she's now come forward to help others forced into prostitution, by teaming up with an international human rights groups.

Daryl said it began when she took a modelling job as a theatre student in Las Vegas.

The 46-year-old told crime show America's Most Wanted that she quickly realised the modelling trip was a scam and she was about to be forced into a sex slave ring.

Daryl explained that she and another girl escaped out a window and fled back to Los Angeles.

But she has always been haunted by the memory of how close she came to being forced into prostitution.

And now she's using her movie dollars to help those who weren't so lucky, after learning there are more than 14,000 girls smuggled into America annually from Eastern Europe and Asia who become part of secret sex rings.

She said: "The more I learn, the more I am moved to take action."
