Mask

A man in a dark coat adjusts a strap on a brown leather bag, revealing a dog's head inside, against a red and white checkered floor. The scene shifts to a man in a white jumpsuit smiling while handcuffed, then to a man with a beard pointing forward, followed by an aerial view of people on a large checkered surface, a woman with headphones walking with a man in a lab coat behind her, and finally a close-up of a diagram on a box showing a human figure.
