Maniac

A man's intense eye fills the frame in a dark, red-lit setting, followed by a close-up of hands securing a knife in a belt. A woman with long, wavy hair stands in a dimly lit space, then a woman's legs walk in high heels on a patterned floor. A man screams as he shatters a glass surface, and the sequence ends with a close-up of a hand gripping a textured object.
