A man who ruins relationships for a living may have finally found a woman he can't easily manipulate in this French comedy from writer and director Pascal Chaumeil. Alex (Romain Duris) is a handsome man who knows how to make women fall for him, and he's found an unusual way of making money from this talent -- guys who want to break up with their wives or girlfriends but lack the nerve can hire Alex to woo them away, and once the women have given their men the bad news, Alex makes himself scarce. While Alex has built a lucrative cottage industry from this scheme, business has been in a slump, and when he's given an especially difficult assignment, he takes it against his better judgment. Juliette (Vanessa Paradis) and Jonathan (Andrew Lincoln) are both wealthy, attractive, and deeply in love, but a third party wants to stop their upcoming marriage and hires Alex to pose as her bodyguard in Monaco as she arrives a few days before the wedding. However, no matter what Alex does, his efforts backfire and Juliette seems immune to his charm; even worse, the harder he tries, the more he finds himself falling for her.
