"Some nightmares don’t happen when you sleep — they live where you do."
In Sleep Tight, the quiet elegance of a Barcelona apartment building hides a darkness that moves unseen. César, the concierge, greets residents with a polite smile each day — but behind closed doors, he is consumed by a twisted desire to spread misery. Unable to feel happiness himself, he makes it his mission to poison the lives of others, one calculated act at a time.
His latest target is Clara, a cheerful young tenant whose unwavering optimism becomes an obsession for César. As he infiltrates her life in ways she cannot detect, his tactics grow more invasive, more dangerous, and more intimate. The walls of her apartment — meant to be her refuge — become the very place where her safety unravels.
The tension doesn’t come from loud scares or supernatural forces, but from the sickening knowledge that César is always there, watching, waiting, and stepping just close enough to avoid suspicion. The audience is trapped in his perspective, forced to witness his manipulations and the ease with which he erodes trust. Every interaction, every seemingly harmless gesture hides a cruel intent.
Director Jaume Balagueró crafts a slow-burning nightmare, turning the everyday into the unbearable. By the time the film reaches its chilling conclusion, Sleep Tight leaves you questioning not only the people who serve you, but also the hidden malice that might already be inside your home.
