Movie very faintly in my memory

I can’t quite remember every detail about this movie because I saw it at my grandparents house when I was a kid and it scared me so badly my parents had to come get me.

I remember there was two girls, one girl was holding the other girl hostage. The hostage saw an officer of some sort coming to the door and she tried to get his attention but when he looked up the captor waved at him and the camera pans down to see her holding down the hostage. Then I remember the captor pushed the hostage down whispering “Please!” and the captor yells “Please what? Please nurse you back to health?”

I also remember the captor watching a video of her kissing a guy and playfully pushing the camera away and she’s watching it crying. The hostage is heard crying in the basement.

I don’t know if this is from a show or a movie but it has driven me crazy for years because I cannot for the life of me remember. If anyone has any idea please let me know!
