The glowing, glitchy title 'OBSESSION' against a black background.

The ad opens with the title 'OBSESSION' in glowing, glitchy text. It then shows quick cuts of a young man looking distressed, driving a car at night, and a woman speaking. A Rotten Tomatoes score of 97% is displayed. The text 'THE BEST REVIEWED HORROR MOVIE OF THE YEAR' appears over scenes of people watching TV and a dimly lit room with pills scattered on a table. The word 'HAVE' appears in text, followed by a man looking at a wall covered in tape, and a man with blood on his face. The ad ends with 'NOW PLAYING ONLY IN THEATERS' and company logos.
