Ghosts (2006)

A young girl, Ai Qin, pays $25,000 to be smuggled into the UK in order to support her family back in China. She is forced to live with eleven other Chinese in a small house in Thetford, Norfolk, working in factories and fields preparing food. The film was inspired by the Morecambe Bay tragedy of 2004, when a gang of Chinese cockle-pickers found themselves trapped tide coming in.
