Every year, Patty and her husband, Sam, invite their closest friends up to their lake house for a weekend of relaxation and booze. But this year is different. This year, Patty and Sam are getting a divorce. So the weekend is still on - just minus one adulterer...and plus one psychopathic killer, trying to take out the friends, one by one. But don't think they won't try to fight back. Just because they’re old, doesn’t mean they’re done living. SCREAM meets BOOK CLUB.
