In this chilling short horror film from director Anthony A. Labriola, an unsettling encounter shatters the quiet of a seemingly ordinary night. The story follows a solitary individual whose routine is abruptly interrupted by an unexpected knock at the door, leading to a tense and unnerving confrontation with a mysterious stranger. As the protagonist tries to make sense of the visitor’s cryptic intentions, a creeping sense of dread takes hold, blurring the line between reality and paranoia. The film masterfully builds an atmosphere of claustrophobic suspense, using its tight runtime to amplify the psychological tension. With minimal dialogue and a focus on eerie visuals and sound design, "Who's That?" explores the primal fear of the unknown and the vulnerability of being alone. This gripping short delivers a compact, nerve-wracking experience that lingers long after the final frame, leaving viewers questioning what, or who, is truly on the other side of the door.
