Invisible : Britain's migrant sex workers

Adapted into the Channel 4 documentary 'Sex: My British Job' by Nick Broomfield. Ming and Beata share neither the same language nor cultural background, yet their stories are remarkably similar.

Both are single mothers in their thirties and both came to Britain in search of a new life: Ming from China and Beata from Poland.

Neither imagined that their journey would end in a British brothel.

In this chilling expose, investigative journalist Hsiao-Hung Pai works undercover as a housekeeper in a brothel and unveils the terrible reality of the British sex trade.

Workers are trapped and controlled - the lack of freedoms this invisible strait of society suffers is both shocking and scandalous and at odds with the idea of a modern Britain in the twenty-first century.
