Xavier Lombard is a French private detective living alone in London with a heart-full of bitter
memories. Once a valued member of a
Paris narcotics squad, he is now reduced to spying on behalf of
jealous husbands and supplementing his fees by shaking down their unfaithful wives.
But when he is given a tip from one of his old colleague, he plunges into an underworld even he isn't
prepared for.
