Frontière(s) (2007)

A gang of young thieves flee Paris during the violent aftermath of a political election, only to hole up at an Inn run by neo-Nazis.

The plot with some contrived political overtones is merely an excuse for a gore fest; fans of the genre might enjoy it.

The Divide (2011)

Survivors of a nuclear attack are grouped together for days in the basement of their apartment building, where fear and dwindling supplies wear away at their dynamic.

Intense closed-room drama with some nasty scenes and a lot of over-the-top performances.
