What is the name of this movie?

I saw this Movie on Hbo in 2009 in China, it was a really great movie. I think it was called "The search for" and I can't remember the last word. It is the name of some french town or village that was destroyed by nazi germany in world war 2. It also might have had "Letter" or "Message" in the title.

The plot involves a man that is searching for a town in france that doesnt exist anymore and was somehow spurred on by his recently dead grandma to find it. eventually he gets to where it used to be and finds a plaque dedicated to the people that died there during the nazi germany invasion.

So what is the name of this movie??
