This espionage story finds Laura (Ira von Fuerstenberg) as the wife of a ringleader of international spies arriving in Berlin for a holiday. While her husband (Paul Hubschmidt) is away, she falls for the British photographer Roger (Gerald Blain). They share a cab -- and eventually each other -- in an adulterous affair at a posh hotel. The two soon jet off to Nice, but word of the affair has reached Laura's ruthless and now Laura-less husband. The spies -- who are now being blackmailed by Roger and figure he knows too much -- go after the couple. Her husband rightfully figures Laura has told Roger enough to warrant them both targeted for execution. The title of the film comes from the DeLuxe Negresco apartment the paramours rented in their ill-fated trip to France.
