Toiling silently amongst the residents of a Barcelona apartment block, doorman Cesar harbors a dark secret: his sole desire in life is to make others unhappy. When he sets his sights on Clara, one of his building’s cheeriest residents, his sick need blossoms into a full-fledged obsession.

After his horror classic REC, Spanish director Jaume Balagueró managed to please genre fans once again with this unsettling thriller. Fueled by a superb performance by Luis Tosar, Sleep Tight manages to build suspense effectively while challenging audiences’ loyalties and expectations.
