A Chinese-American lesbian and her traditionalist mother are reluctant to go public with secret loves that clash against cultural expectations.

Interpol detective Wilton, known for his powers of deduction, is set on a gang of bank and jewel robbers who are up to mischief in Marseille. Despite some false leads, he can shed light on the murky affair. A conventional but relatively exciting crime film that strives for atmospheric density but is not immune to the clichés of the genre. Charpentier's trivial novel is the first crime thriller in a series that pretends to be the publication of Commissioner Wilton's diaries.
