Alex (Duris) and his sister break up couples for a living. From Morocco to Monaco to Paris, no location is too far and no challenge is too great. With a 100% success rate, they’re at the top of their game. However immoral their profession may seem, there are some rules that render it quite honorable:

Rule 1: Never break up a happy couple.

Rule 2: No falling in love.

When a wealthy man hires them to break up his daughter and her boyfriend, the rules start to bend. After a thorough investigation, there is no doubt that they are the perfect couple. Money problems, however, cause them to take on the job (violation of rule #1). After a couple of days with Juliette (Paradis), even Alex, the most professional of professionals can’t resist her allure (violation of rule #2). It’s looking like the agency’s reputation is at stake, and for the first time ever, the heartbreaker risks being the victim of a broken heart!
