In Her Skin (1969) on Netflix

This is what every parent fears: their child not coming home when they're meant to. When the fifteen-year-old student, Rachel Barber, doesn't climb off the tram to meet her dad, Elizabeth, her mother, and Mike, her dad, bolt into action.

Consumed with self loathing, 19-year-old Caroline covets, stalks, abducts and then murders 15-year-old Rachel Barber whom she considers "perfect." Rachel's disappearance triggers an electric reaction from her parents and her boyfriend. Later, the police misinterpret Rachel's disappearance and believe she simply ran away from home.

Fifteen-year-old, Rachel Barber, seems to have it all. She's a brilliant student, an excellent ballet dancer, and all in all, she's the perfect daughter. On the other hand, her unkempt, nineteen-year-old former babysitter, Caroline Reed Robertson, is struggling with depression and psychosis, seeing in Rachel everything she wishes she was. But, when on Monday, March 1, 1999, Rachel fails to return home, tragedy strikes. Indeed, Caroline hates herself, and she would do anything to be like Rachel and have everything she can never have. What has she done?
