Parasite...

Two men stand face-to-face in a dimly lit room with a large window, one holding the other's shoulders. The scene cuts to a close-up of a man's face cracking like shattered glass, then to a grotesque, monstrous head emerging from behind him as he is held, followed by a shot of their feet on a wooden floor, and finally a violent explosion of blood and debris from the back of the man's head.
