Dinner parties tend to suck, don’t they? You bring a stupid bottle of wine nobody will like. You have no small talk for others gathering at the table other than the weather and your stinky feet problem. Your hosts may or may not be trying to kill you.

Will (Logan Marshall-Green) is visiting his ex-wife Gina (Michelle Krusiec) for a dinner party. Gina has been away for some time, and she’s gotten all smiley in the wake of a tragedy she and Will suffered. Her new boyfriend David (Michiel Huisman) is a bit of a weirdo, all happy and perhaps a bit too pleasant. In contrast to his pleasant demeanor, he shows the party a video of a woman, surrounded by members of some cult, dying by choice. That puts a strange damper on the party, but they all eventually make it to the dinner table, where things get even weirder.

Director Karyn Kusama (Jennifer’s Body, Girlfight) does nice work within the scary cult genre, getting good performances from Marshall-Green and John Caroll Lynch as a friend with a sketchy past. There’s a good mystery at play here, with a final act that delivers on the build up. It’s a good ensemble cast in service of a decent script and effective director.

Marshall-Green, best known for a supporting role in Prometheus and a couple of TV shows, should find himself getting some decent future work in this one. He’s got some major chops.
