A love story conceived as a thriller. A gentleman… An English gangster, Valentin, sets sail from Fécamp on a magnificent sailboat, alone on a trip around the world ; more to leave his past behind than to escape from the police. As a master of disguises and hold-ups, Valentin – a kind of Lupin-Frégoli – signed his name to a few exploits of the genre by robbing some of the largest jewelry stores in the world, brilliantly wielding only two weapons, bluff and humor. Meanwhile, in a Moroccan palace, Jane, a burnt out jazz singer, croons her “blues” amidst the general indifference of lounge lizards.
