70/80s? Movie about little girl in woods

I only remember this one scene where a young girl is walking in the woods at night finds a cabin ripped straight out of little house and is invited in. The couple let her sleep in the loft (again exactly like little house on the praire) with their 2 daughters. She then over hears the wife telling the husband to snap her neck  so she takes the sleeping bonnet off of one daughter, puts it on, the man climbs the ladder and ends up snapping his daughters neck and little girl escapes.                                                               I saw this movie in the late 90s on TV at 2 am. It had a dank look to it which makes me think its from the 70s/80s. It was in color and in English. Thanks.

Got something to say?
