The opening scene shows the main protagonist Somerset in bed, unable to sleep due to noise from the next room. Shots show his frustration and attempts to focus on a metronome to block out the noise. This microcosm represents his desire to escape the noise and disruption of city life. The transition to the opening titles is abrupt, leaving the viewer feeling something is missing. The titles use an uneasy, flickering font and fast editing to set an unsettling tone and prepare viewers for disturbing visuals and an exciting thriller.
