The best Serge Gainsbourg’s action movies

Serge Morgan is a killer working for the American Mafia. After performing a contract in New York for his employers, he takes the plane back to Paris and, during the flight, he gets to know Jane, the rich daughter of an ambassador. Once in Orly Airport he gets seriously wounded by the men of French drug kingpin Henri Emery. He manages to escape them though and takes refuge at Jane's. Passion sets in between the killer and the young lady. As of then, sex will be intertwined with blood and death. For better or worse...

The good news is that at last a scientist has discovered a way to disarm all the nuclear weapons in the world. The bad news is that he doesn't have altruistic intentions with regard to his new invention. Fortunately for fans of somewhat (?!) improbable spy movies, the professor is being sought by agents of both the Russians and the Americans, among others. The evil old professor has been keeping his daughter under wraps, almost a prisoner. He has also been keeping a mysterious sea monster in a pool on his estate, for reasons which remain unclear. What is clear is that somehow the professor's daughter will be saved, he will come to a bad end, and the world will be saved yet again from mad scientists.
