Until a few months ago, George, was a director of a London bank, but having done something reprehensible, dishonourable and possibly criminal, he has deserted his wife, and fled with his girlfriend, Susanna, to a remote Greek island. While travelling back to England, Susanna is caught up in a people smuggling operation. George reluctantly travels to join her, but before they can be reunited, he resolves to track down the traffickers and help the women and girls who are being sold onto London's sex scene.
