The A24 logo followed by the title 'undertone' and the ominous phrase 'ONLY IN THEATERS FRIDAY THE 13TH'.

The video opens with the A24 logo, then transitions to a woman wearing headphones in a dimly lit room, speaking into a microphone. The scene shifts to close-ups of a microphone, abstract imagery, and a digital interface showing audio files. There are quick cuts of unsettling images, including a clock showing 3:00, a dark staircase with a cross, and a person touching a screen. The woman appears increasingly distressed. The final scenes show the movie title and release date.
