I watched a movie about, a girl who worked for this company, the company tried to do something illegal, and she was trying to tell someone about it, I guess. The people at the company intoxicated her with fumes of something, and in the beginning, shes sick from the fumes. She was going to go to the doctors, but right when she stepped out of her door, she was shot right next to her father. Later on the father tries to find out who killed his daughter. He goes through a bunch of people asking questions and threatening them. In the end, he killed this rich guy, first he poured intoxicated milk(from the fumes) on him, the rich guy dragged himself to the kitchen to get the medicine so he wouldn’t die, before he could find it, the father shot the guy.
Any idea what this movie is called?..
