To me when I was watching this movie, it seemed like a bad remake of Steven Spielberg's "Duel" With the psycho truck driver. Only now its a cop, and instead of one guy, its two girls.
This movie as whole was just bad, the acting wasn't good, the dialog was poorly written, and it was pretty predictable from time to time. And I think one of the reasons for the predictability is that they started it with the end, but didn't do it properly like "The Usual Suspects" or "Memento" which still left you guessing as to everything else even when you got to that scene.
My recommendation is to stay far from watching this movie.
