It's the story of an FBI agent who tries to catch a serial killer which kills his victims faster or slower depending on the visitor-counter of his Live-Stream.
I've to say that i'm impressed that this movie did not suck. I expected it to be totaly inacurate(full of technobable etc.) and to be boring but I was proven wrong.
It's actualy a nice movie to watch, not life changing but nice.
