DON ANSELMO slowly turns his head 180 degrees. His neck does not crack. It squelches .

1. Logline When a young professional moves into her dream apartment, she realizes the elderly man next door isn’t just eccentric—he is the landlord of the damned, and silence is the only rent he accepts. 2. Synopsis The Premise: Vecino Infernal explores the psychological and supernatural horror of thin walls. The protagonist, Lucía , a sound engineer seeking peace, moves into a rent-controlled building in a crowded city. Her next-door neighbor, Don Anselmo (The Vecino Infernal), appears to be a frail, bitter old man who complains about noise at all hours.

Lucía tries to be accommodating, but soon realizes Don Anselmo’s rules are impossible. He can hear her heartbeat when she exercises. He bangs on the wall if she flushes the toilet after 10 PM. When she adopts a small dog, the dog goes missing—only for her to hear a faint scratching coming from inside Don Anselmo’s walls.

LUCÍA "I was moving a chair."

He doesn’t look at her. He stares at the space between floor buttons.
