A deer breathing fire with glowing red eyes.

The ad opens with a deer with glowing red eyes breathing fire in a warehouse. It cuts to two people in orange jumpsuits looking shocked, with text identifying Joe Keery. Then, a person is seen lying on the ground in a puddle, seemingly attacked. Next, Liam Neeson appears, looking stern, with text identifying him. The two people from before are seen again, looking scared, and then Georgina Campbell is identified with text as she fires a weapon. The ad ends with a title card for 'Alerta Apocalipse' and credits.
