She is inside a car, she has moved herself to a position as close as possible to the door and is pulling the internal door handle with a short jerky movement. She has already done this many times (a million is probably an exaggeration).
We don't have the rest of the context but I would guess the woman is scared and is locked/trapped inside the car and is frantically trying to get out. The fact that she has wedged herself as close to the door as possible suggests to me that there is someone or something in the car that is frightening her.
Or she's leaning against the outside of the car, frantically trying to get it open.
That is a possibility I hadn't considered, but only because I don't feel it's natural to "wedge yourself" against something from the outside. You could be right though.
Having said that, wedging herself against it from the outside may well thwart her attempts to get it open. If she is leaning her entire body weight against the car door, it probably won't open even if she successfully activates the door handle.
You pull the internal handle of a car door too! At least if all her weight is against the door from the inside, if and when the handle finally works and the door flies open outwards, her weight will be pushing in the right direction and will help the door open even faster.
The way I'm imagining it, she's not pulling the car door, she's pulling the small handle on the inner panel of the door to open the door from the inside.
