what's the title of this french movie?

Can somebody tell me the title of this film.I do Know that it's French
movie.The story goes like this:
The film opens with a young woman walking on the road and she gets
kidnapped.The father of that girl owns a very big company.All his
efforts to find his daughter yield no results. It is then that he
decides to send one of his employees (lead actor of the film) on the
mission to find his daughter.The reason for this is that his daughter
is an unlucky girl and the only person as unlucky as her is this
employee.He confirms that through a series of tests(funny).Now the
hero is asked to leave for a place which the boss's daughter was
supposedly going to before she went missing.The Boss hopes that this
guy being the unluckiest guy,would meet the same fate as his daughter
and hence would go through same events that his daughter had gone
through and there is fair chance that he will meet his daughter.At the
end the guy finally makes it and finds his boss's daughter.
And the film ends with both the hero and heroin standing on a raft and
the raft cuts loose and drifts away.(Double unlucky).
I would appreciate if somebody could let me know the title of this
FRENCH FILM.I've really tried and couldn't find out.

Thanks.
