I have the weird memory of watching this movie as a kid but no one I ask has any idea what I’m talking about. The only things that I can remember about the movie is at the beginning some weird underwater scene with two kids and a mom. I kind of feel like one of the kids was like a robot or a misfit in the family? The other scene I remember is the misfit kid going into the parents room at night and cutting the moms hair or almost cutting her hair.

It was in English and was a color movie
