Murdering teens in the sewers

I think it was set in Paris. A group of teens hung out in the sewers. I think some tourists ran into them and were killed. The only concrete thing I remember is the last scene. A woman was crawling out of the sewer in the side of a hill. It looks like she escapes. But then she is dragged back inside.

Catacombs (2007)?

The description of the final scene made me think of the closing stages of Ils [Them], set in Romania not France though and probably not what you are looking for anyway but might as well throw it out here just in case.

Sounds like the movie "Them".

Does not look like Catacombs. The last scene in that one, she survives. But the scene I am thinking of could be in the middle of the movie.

It does sound like "Them". The scene at 1:30 looks like what I an thinking of. I have to find a place to watch it before I mark as answered.

Found it on Vudu. Yes, "Them" has to be the one I am thinking of. Thanks all.
