A woman stands in front of a glass door with the word "KILLER" written in blood, her expression one of shock and fear. The scene cuts to a man with blood on his face, first looking down with a pained expression, then smiling widely with fangs, followed by a close-up of his face as he snarls with glowing yellow eyes and bared fangs. The sequence continues with a woman with blonde hair screaming with fangs, and a man with blood on his face looking up with a determined expression. The setting appears to be a dimly lit interior, possibly a house or a room with bookshelves.
