Laura Tracey is an ordinary, modern woman, a wife and mother working for a big merchant bank in London. When she exposes her employers, who are laundering enormous amounts of dirty money, she puts herself and her family in grave danger. They are forced to accept witness protection, and are catapulted into new identities and a new, alien environment. The authorities protect Laura but her integrity is vigorously questioned when the Bank's defence lawyers reveal a much more personal motive for her actions - one that looks suspiciously like revenge.
