On Halloween night, six friends go to a bar, and later drive around looking for a haunted house (or "haunt"). They find one, and go inside. Things soon go very, very badly. And... I guess that's really all I want to say about the plot. It's a pretty simple movie. But as slasher movies go, it has a somewhat interesting premise. I mean, not super interesting, but still, having the killings take place in a haunt on Halloween isn't bad. It makes for all kinds of possibilities, while keeping everything in a relatively confined area.
