Laure Peskine has explored the web and found the following addresses about the last Ken Loach film.

The film features a woman who suffered from discrimination and harassment in her workplace and started her own temporary worker company where she ends up exploiting people in her turn. Does money corrupt all? Can the abused become abusers? "In a world where anything is possible, it's easy to lose everything".
