The opening sequence shows a mixed race male detective exiting a building and car and arriving at a crime scene. Cutting between the detective and a distorted male in a confined bloody space, the detective examines a dead body while the distorted man watches frantically. When the body bag is opened, the detective believes the dead person is himself, but sees it is actually a young woman. The sequence uses conventions of the thriller genre like a detective character and disturbing clues, but subverts expectations by making the protagonist and antagonist the same person.
