A renowned American mobster, Morris Lampke, and his widowed half sister, Anita Duvallier, arrive in Paris, apparently with a mob contract on his head before he can testify in front of the US Senate Committee on Organised Crime. James Gottoro, his bodyguard and friend for over 30 years, is shot dead upon arriving in Paris and is brought out on the airport luggage convey belt. That leaves little doubt in the mind of his half sister who that message is intended for. She goes to see Alexander for his help without her half brother's knowledge or consent. She also reveals to Alexander that many years ago when Alexander needed some money, a fairly sizeable amount, the mobster put it togather for Alexander. Alexander agrees to help Morris Lampke solely because of his sister.
