Looking for the name of a german film.

HI everyone. I'm looking for the name of a german film that I haven't seen before. It came out around about 2002 to 2004 possibly.
It's set just after WW2 and it's about a couple of german spys on the run with their daughter. All I know is that the daughter falls in love with a boy and he betrays them. Kind regards. Bb

Lore

I dont think its "Lore". I rewatched that recently and that was not the premise of the film. I dont want to give away the story of the film for "Lore" and spoil for those who havent seen it yet.

I'm afraid it isn't either of them they are too new. It was at cinemas about ten or more years ago.

Good suggestions however.
