A survey of the happenings in Guantánamo, Cuba during nighttime. We see neighbourhood watchmen on lonely streets, bustling crowds of revellers in illuminated squares, families as they relax at home by the glow of their phone and television screens, and workers as they toil through the night. Whilst there is no dialogue in the film, captures the rich nighttime soundscapes. With a keen eye and acute ear, Guardians of the Night contributes to the growing body of sensory ethnography, illuminating our grasp of the feeling of a Cuban city at night.
