The only scene I remember is that there is a girl watching tv at home alone. On the tv, she watches a documentary on how to save someone’s life that is choking/can’t breathe by stabbing a ball point pen into their neck. The next day she does this to an actual person.
I believe the actress was Sandra Bullock, but not 100% sure.
Watched the movie probably 5-10 yrs. ago. It was in color.
Let me know watcha got!
Sounds like the heat. Here is the scene https://youtu.be/qd38gmuBb0E
