parents go away, come back to deserted town, kids are gone

okay so the parents (the mom is blonde i think?) go away for a weekend and come back to a deserted town. then there's some more stuff but they get their kids back but there's this guy who is terrorizing them and there's one part where the kids are eating at a table and the dad says it's gonna be fine because he set up motion sensors but then he hears someone drilling so he takes the kid's knives and forks and they all go hide in the bathroom upstairs? someone help me figure this out.
