A young woman inherits a vineyard, but a company wants to bankrupt her. A young man comes to stay with her; he’s a bit strange (possibly autistic). There’s a scene where, the morning after his arrival, the woman enters the living room and finds that he has neatly arranged all the items in their places.

I also remember a scene where they save the vineyard from frost together by placing barrels in the field and lighting fires in them to prevent the grapes from freezing.

At the end of the plot, the guy hacks into a bank and transfers funds to save the vineyard from bankruptcy.

I watched the movie about 10 years ago; it might be French.
