Oscar-winning actress Emma Thompson has used her own money to bring a show about sex trafficking to the Fringe.
The play uses verbatim accounts from two women trafficked separately into Britain.
Although Thompson does not appear in the show, she is expected to visit Edinburgh during its run at the Pleasance and has agreed for her name to be used in its title.

A sporting theme can also be detected in the programme, which includes All Over A Football at the Underbelly, Bob Doolally's World Cup Balls at The Stand and Paul Ricketts - Kiss the Badge, Fly the Flag! at Just the Tonic @ the Caves.
Following the success of the First Made in Scotland programme in 2009, which secured nine awards, it returns this year with the best of Scottish theatre and dance.
It is supported through the Scottish government's Edinburgh Festivals Expo Fund and helps talented, Scottish-based performers and companies present their work on an international stage.

'Excite and delight'

"Nowhere else can you see such a variety of world class talent and range of shows that are guaranteed to engage, enthral, excite and delight.
"As the largest arts festival, the Fringe attracts performers and audiences from every corner of the world. I look forward to welcoming them to Edinburgh and kicking off what is set to be the biggest and most exciting Fringe to date."
