I remember this movie playing on the scifi channel when i was a kid, probably 2003-2006, where 6 kids go to this small town to vacation at this house that one of the kid's uncle owns. They were in college I believe.
There was a black guy, a redhead girl, a couple and a brunette as well as the main character. When they get to the house there's all this metal around it, like above the door.
They find a jar with an aliens hand in it in the basement and it twitches. The redhead goes missing first, then the black guy, then the aliens start beaming into the house and one of the guys is halfway standing on the beam and is cut in half down the middle. Finally the last three kids escape in a truck.
