Usually cast as secret agent/private eye Lemmy Caution, Eddie Constantine plays "Eddie" in The Empire of Night. This time, Constantine is a cabaret singer at odds with a criminal gang. When the villains try to take over every nightclub in town for their own nefarious purposes, Eddie sings a new tune with his fists. The story takes several unexpected turns, but Constantine remains in charge throughout.

The Marquis de Villemaur reunite strange visitors in his Castle, to meet a survivor of the Third Reich. There is an Italian fascist, Heinrich; a German, Matthias; a Russian; and Dromard, a blind French war hero with a black monocle.

In this French espionage thriller, Eddie again plays the role that made him a star, Lemmy Caution. Lots of two fisted action.
