"who is dead?"

A young man with brown hair lies on the ground, screaming in pain as blood stains his face and shirt. The scene cuts to a dark room where a young woman with dark hair and glasses, also covered in blood, holds a knife above her head. She then looks down with a manic grin, blood on her face. The sequence continues with a close-up of a bloodied knife held by a hand, followed by a shot of two young men in blood-stained white shirts standing in a dimly lit, burning room, one with his arm raised.
