Answer: Saw
Immensely graphic, extremely violent and ultimately gripping are the best ways to describe "Saw". When two men, Adam (Leigh Whannell), and Dr. Lawrence Gordon (Cary Elwes), wake up in the cell of a serial killer, they have no recollection of how they got there, or how long they had been there for. To make matters worse, there is a dead body lying between them, and they are handcuffed to pipes. The two must then find a way to escape, and save the Doctor's family, who have been kidnapped by the killer. The tag line relates to the sickening ultimatums that the killer forces upon his victims. It is a good fit for the movie because it gives the audience an idea of what to expect from the film.
