5 second plot: Erin is with her boyfriend at a family get-together (his family). All of a sudden they are under attack by a group of masked men that want them dead. Family members start dropping like flies, but Erin is not taking it and fights back.
5 second review: Now that's what I call a decent slasher-movie. Great suspense, nice twists, cool killings and blood splattering all over the place. That's the way to do it.
