Turno Nocturno

Marcos, a security guard at a derelict nightclub, receives a cryptic warning from his predecessor: "Never answer the door after 3 AM." His first shift descends into nightmare when a rhythmic knocking begins, perfectly synced with his own heartbeat. Surveillance cameras show only empty hallways, yet a pressure builds in his ears. Slowly, Marcos realizes the building breathes, and the old rules aren't superstition—they're a survival guide. Each night erodes his sanity, blurring the line between paranoia and a very real threat waiting just beyond the door.
